    1. That smell hits you the moment you open the microwave door, maybe it’s last week’s fish dinner, or burnt popcorn from movie night, or anything unidentifiable that’s been lingering for days. Don’t worry, you don’t need to live with a microwave’s odor, and you definitely don’t need to replace your appliance just yet.

      Over time, dust and oil can clog up in the bearing and along the track that the segment glides up and down on causing this sort of issue. You can flush it out with mineral spirits (or something similar) while you actuate the shift key to remedy the issue. When you're done, then add back a drop of light (sewing) machine oil.

      While you're at it, most basket shift machines load them with large springs to assist with the weight and to help the return. They're typically attached to metal brackets that can be easily formed with pliers to either increase or decrease the force as necessary to suit your touch and preferred response. (YouTube videos may help here if necessary.)

      If that doesn't remedy it, then take the hood off and look closely at the mechanism to see if something is physically impeding it.

      There are two general types of "sticky keys": 1. sticky going up 2. sticky coming down

      Sticky going up

      For stickiness slowing down the typebar (on the way up or down), it's likely that you've got oil, dirt, dust, or other sludge in the segment of your machine. You'll want to flush out your segment with some solvent and potentially blow things out with compressed air to remove the source of the friction.

      While you're flushing out the segment with your solvent of choice (lacquer thinner, paint thinner, mineral spirits, alcohol, etc.), actually move the typebars using the keys or by other means. This will help to get them moving and allow the solvent and subsequently compressed air to help flush the oil, dust, hair, etc. out of your machine. You've already got a mechanical cleaning device of sorts (the typebar itself) inside the segment, so move it while you're flushing it out!

      It may take a few repeated treatments/attempts to get it all clear for all the keys, but it's far easier than taking everything apart.

      When you're done, it's common wisdom that one should NOT oil the segment.

      Sticky going down

      If your typebar(s) are sticking due to friction at the typing point, then they need some gentle forming to the right or the left to prevent them from rubbing on the typing point so that they can fall back down to the type rest. The two videos below will help describe and demonstrate the symptoms as well as the repair. - https://www.youtube.com/watch?v=qrlt6VyC8D0&t=485s - https://www.youtube.com/watch?v=Arspyq1w4Iw

      Other considerations

      It's much less common, but once everything is clean and properly aligned, if you're still seeing sluggishness, it may be the case that the spring on the individual key has broken or become disconnected which prevents it from returning back to the type rest.

    1. https://www.reddit.com/r/typewriters/comments/1lu9173/turns_out_mineral_spirits_are_illegal_in/

      Traditional mineral spirits are illegal in some states in the US including California. As an alternative odorless mineral spirits are low VOC, safer, and a solid alternative. Typewriter shops like Typewriter Justice in Keller, TX recommend it. Some who have access to cheaper mineral spirits still prefer the odorless version for the reduced residual smell.

      Nashville Typewriter, another shop, recommends camping fuel (aka white gas) which is mostly naphtha. Zippo lighter fluid is primarily naphtha, but is much more expensive. In Germany, it goes under the names of Testbenzin or Reinigungsbenzin.

      Jennifer Colombo, a repair person of Colombo Collection suggests linseed oil to clean and protect metal surfaces and create a barrier against rust and oxidation.

    1. Not clean enough. There is only one solution, you take the body panels off and clean it. The keys here need cleaned with a 50/50 mix Simple Green and water. The comb area gets cleaned and blown out with mineral spirits. The basket gets cleaned, carefully, with lacquer thinner. If the insulation is really bad, you take it out and glue in new. I like EVA foam. But I will wash the insulation with SG and water and rinse it in the sink and then let dry and retest if it is in good condition otherwise. Case insides can tolerate some water if you don't like soak it. I use a pet spray, scrub it fast, rinse and get it dried off fast Then out in the sun or a fan blowing on it. Once it is dry, if it still smells, I take a few paper towels, spray Glade air freshener in them, set it in a tin foil pan and into the case. Then out in the sun closed up. That will kill most anything.

      u/jbhusker's cleaning out a typewriter

    1. This typewriter was quite grimy, so I removed the shell (fairly challenging) and gave it a bath in an ultrasonic cleaning tank. Mitch Hamm alerted me that such tanks, big enough to dip a portable while keeping its keys out of the water, are now available for a mere $150 or so. Here’s the Royal undergoing what sounds like electroshock therapy, but is really just a micro-agitated bath. Concentrated Simple Green Industrial Cleaner & Degreaser was added to hot water in a 1:20 ratio.

    1. We switched to Ultra 3 detergent after using Dawn detergent for years. A quantum leap in effectiveness. When we got the new Ultra 2100 cabinet ultrasonic unit it came with a gallon of detergent. We used it ONE TIME and the parts came out so much cleaner, almost brand new. The detergent is expensive, yet we've never gone back.

    1. We are often asked what ultrasonic cleaners we use in the shop. We have three. The large cabinet model that holds large typewriters such as Selectrics, a medium sized 12"X20", and a smaller cleaner 10"X12". The medium and smaller ones you can buy on eBay all day. The models change, and the sizes are all similar. The medium sized cleaner is used for small to medium sized typewriters and the small machine is mostly for nuts, screws and other tiny stuff.

    1. Try a toothbrush with a long, thin handle and a small head.

      The brushes sold with many metal and rubber straws or thin bottle brushes are also excellent for reaching into places like this. Sometimes you can find similar thin brushes in the baby bottle section of big box retailers or specialty stores doing baby goods.

      Similarly a plastic oiler with mineral spirits in combination with an air compressor/blow gun or canned air is also a solid way to go.

      Long handle cotton swabs can also be used if necessary.

    1. reply to u/Omega48boar at https://reddit.com/r/typewriters/comments/1knsgn8/pressure/

      I was wondering what the upper limit psi would be for blowing out the gunk using an air compressor.

      The highest air compressor pressures may be determined by your particular compressor's (or air canister's) maximum output as well as the maximum suggested output for any accessories you're attaching to it. Many basic air gun attachments have a max PSI of around 100 PSI even when the compressor will produce much higher outputs.

      Generally I find that for most benchwork on typewriters anywhere from 50-100 PSI is generally more than sufficient.

      Depending on the condition of your surroundings, I recommend putting a towel (or similar material) underneath your typewriter with a solid backstop so that if any springs, screws, or other valuable parts are blown loose, they're caught pretty quickly by the towel rather than flying across the room or down onto the floor out of sight.

      Higher pressure settings may be useful in some cases. One should always take care to be wearing protective garments and eyewear to prevent being spattered with caustic chemicals. Similarly protecting plastics, paint, and decals on your typewriter with appropriate cover is advised with some solvents.

      Operating the compressor, which can cause sparks as well as heat, at a reasonable distance from potential flammable vapors is also a mandatory safety precaution. Using volatile solvents frequently seen in typewriter cleaning procedures should only be done in the open in a well-ventilated area using appropriate masks to prevent inhalation of vapors. Long term exposure to vapors of substances like lacquer thinner can cause lung damage, COPD, and other adverse health effects.

      For extended usage pending the sorts of air gun tips which might be used for typewriter cleaning, one is also well advised to use ear protection to prevent long term hearing damage/loss.

    1. Everyone mentioned most of the usual tricks, but one.

      To get your sticky typewriter keys working again, while you're flushing out the segment with your solvent of choice (lacquer thinner, paint thinner, mineral spirits, alcohol, etc.), actually move the typebars using the keys or by other means. This will help to get them moving and allow the solvent and subsequently compressed air to help flush the oil, dust, hair, etc. out of your machine. You've already got a mechanical cleaning device of sorts (the typebar itself) inside the segment, so move it while you're flushing it out!

      For the white, crusty out gassing (or off gassing) on plastic typewriter keys, Duane recommends a round or two of Simple Green with a stiff bristle brush. Follow this up with a scrub down using WD-40 to displace the water from the Simple Green and then follow up with denatured alcohol, which is safe on plastics, and a wipe down with a rag to dry.

    1. In the US, you can get one hundred 4" mascara brushes for around $5. Eye Tees (cottton swabs with a firm point on one end and a flat tip on the other) cost roughly the same. You'll find them at most beauty supply stores or online. These get into tight spaces. Dipped in mineral spirits (or whichever solvent you've come to like), the brush gets the stuff loose and the Tee wipes it away. Blasting air helps as well. Works for me. Others will have other ideas.

    1. Old school repair guys used a lot of different stuff that's no longer available due to being... Not good. Ha. But naphta was one that's still widely available as white gas aka "coleman/camping fuel" Essentially naphtha with stabilizers to keep it from going bad. Mineral spirits works as well, but naphtha leaves less residue in my experience. Lacquer thinner is good for especially stubborn crap and cleaning slugs, but evaporates really fast and the fumes are no bueno. Alternatively; non toxic degreasing cleaners like simple green are usually my preferred method of cleaning up especially gross machines. Typically very safe on paint finishes and internals, just make sure to keep it off the decals. (It can and WILL erase them if it sits for more than 10 secs) Really though, nothing beats air and a long handled "paint" brush. My air compressor and blow out tube are some of my most cherished tools.

    1. Zippo Lighter Fluid (Naphtha)

      While Zippo lighter fluid (Naphtha) is a bit more expensive per ounce than other solvents (mineral spirits, lacquer thinner, et al), it does usually come packaged in a dispensing container that may make it easier to dispense in a directed method into the internals of typewriters for cleaning them out.

      The other benefit is that some may have it on hand for general household use without needing to make a separate trip to the hardware store.

    1. It can be useful to take some mineral spirits, naphtha, or paint thinner and a tooth brush (or, even better, a brass bristle brush) to your typeface every now and then to clean the ink, dirt, paper, bits of ribbon, dust, etc. out of it. Doing it after changing ribbon is always a good idea. If you're really hard pressed, nail polish remover (acetone) or rubbing alcohol and a cotton ball along with a small pin tip for the loops of letters like 'a', 'o', 'p', 'g', etc. can be used.

      How well (or not) your typewriter works from a print perspective can also change with the type of paper you're using, what your ribbon is made out of (usually nylon, silk, or cotton), how much ink it's got in it and how old/worn it may be. A good backing sheet behind your typing paper can also be helpful.

    1. To be more specific on solvents for beginners, potentially try mineral spirits (white spirit in UK), paint thinner, naphtha (lighter fluid), kerosene, varnish remover, PB B'laster, or carburetor or brake cleaner. Be careful as many of these are flammable and some can remove paint or decals; use all of them in a well ventilated area. You may see some recommend household variations of alcohol, but these do contain water and generally aren't very effective solvents for the types of oil/grease/dust you'll probably want to remove; professional typewriter repair shops would not use alcohol on a machine. And for those in the back, no one but a psychopath would use WD-40 on a machine's internals.

      https://www.youtube.com/watch?v=xjumGF9NFE8 is a pretty solid cleaning primer. Searching YouTube will uncover some potential additional advice in addition to what you can find at https://site.xavier.edu/polt/typewriters/tw-restoration.html

    1. it is not mold; it is plasticizers coming out of the plastic. I remove it with various means: alcohol, polishing with a very fine polish, Goo Gone™, naptha, and such.

      The white gunky substances seen on the plastic keys of old, unmaintained typewriters generally isn't mold, but plasticizers coming out of the plastic. These can usually be cleaned off using simple household cleaning products or if necessary heavier cleaners (Goo Gone, alcohol, naptha, etc. - test these on hidden parts first to ensure they don't react with or destroy the plastic or remove the paint of the key letters) followed up by light waxes or polishes and buffing.

    1. WD-40 for Crinkle Finish Typewriters — Does it work??

      https://www.youtube.com/watch?v=nz1t6QtARyI

      WD-40, which has paraffin wax as an ingredient, can be brushed onto the crinkle finish of a typewriter to clean it up and give it some shine. Use a rag to wipe off excess and take care not to get any in the segment comb. The difference on a generally clean typewriter appears to be negligible and primarily results in a WD-40 smell.

      Would something like Armor All work better? Car wax might also work as well. Powder coating polish could work, but it may act as a gentle abrasive as it is also meant to lift stains.

    1. Typewriter Cleaning and Repair Basics #2 Type Bars, Case, and Crinkle Finish

      https://www.youtube.com/watch?v=82O_iUAI5og


      Segment comb cleaning - isopropyl alcohol (gentler solvent) - odorless mineral spirits - Lacquer thinner (maybe a bit too aggressive) - naphtha (lighter fluid) take care for flammability and ventilation

      Work solvent into bearing between type bar and segment comb. To dry things out one can used compressed air when done or just air dry.

      If sticking keys not due to being gummed up, bend portions slightly for better alighment.

      Do not lubricate the segment comb.

      Only lubricate the carriage rails when necessary.

      Exterior cleaning

      Brass bristle or nylon bristle brushes (toothbrushes) can be used to clean the exterior of the typewriter and/or cases with mild detergents or other solvents. Depending on the finish, try the brush and solvent on a small portion to determine colorfastness and potential scratching first.

Clearly, owning all kinds of data without organizing them feels like stuffing your closet with clothes that you should have donated 5 years ago. It is a time-consuming and soul-destroying process for us. Luckily, in R, we have something in R called "tidyverse" package, which I believe the author talks about in the next paragraph, to make life easier for everyone.

WIthout these packages' existence, I have no idea when I will be able to reach the final step of data visualization.

    1. There is a tendency to hold unrealistic expectations regarding “spiritual”leaders and teachers, and likewise for what spiritual practice might eventually do for ourselves. One is that mindfulness and Insightcan somehow magically transcend the causes and conditions that shaped ourlives and personalities. To paraphrase the Buddha, what arises in dependence on causes and conditions onlyceases dueto causes and conditions! Meditation and dharma practice create the specific causes and conditions for certain things to arise and others to pass away–but not everythingwe might wish for. Ihave discovereddeeply embeddedautomatic patterns of respondingin fundamentally unhealthy waysto certain situations. Theseautomatic response patterns are the productof an extreme emotionally, psychologically, and physically traumatic childhood, compounded by coping methods I developed in the decade or so after leaving home at 15. From being a homeless adolescent living on the streets, never attending much less graduating high school, I obtained a PhD andhaveled a successful and rewarding professional and spiritual life. However, those conditioned response patterns and coping strategies that had served me well in a life with such difficult beginningswere ultimately disastrous –in my interactions with my wife,then whenconfronted bythe Board of Dharma Treasure. Within themlies the root of much of my unskillfulness.The personal work and therapy I’m doing now continues to clarify these. Becoming aware of them has allowed me to make progress in overcoming them.What I realized through working with my therapist and a life coach was that, for all my life,I’ve had almost no ability to establish and maintain clearpersonal boundariesin interpersonal interactions. If someone was upset, angry, hurt, disappointed, afraidorwhatever, I tendedtotakepersonal responsibilityfor their mental state. Regardless of the cause, or whether or not I hadanything to do with their being upset.Or even the reasonableness or unreasonableness of their reactions!Iwouldbecome inappropriately over-committed to relieving their distress, and likewise inappropriately over-committed in every other part of my life as well. I havealsobeenextremelyconflictavoidant.When confronted with angerand/or aggression,I woulddo almost anything to placate. Itendedto avoid conflict by beingexcessively compliant, acquiescingtoo quickly, andengaginginvariousconflict avoidance strategies.I too readily acceptedtheviews ofothers,or triedto find waysto side-step issues of conflict, to relieve another’s pain and anger whiledisregarding the cost to myself or future consequences. If attempts to placate failed, and full-blown conflict seemedinevitable, I wouldoften disengage, withdraw, surrender, and even take a beating if necessary.
