Your alcohol is making the old oil and dust fluid again for a while, but without either fully flushing it out or blowing it out with compressed air, the solvent evaporates and the remaining solid oil/dust freezes things up again.

Rubbing alcohol is probably one of the worst degreasers, but people recommend it because most people often have some in their house already. (Depending on the type, it also contains high proportions of water which isn't the best thing to mix with your metal typewriter.)

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 (be careful for splattering and cover the plastic and painted portions of the machine and surroundings with a rag). 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.

2-5 flushes can sometimes be required before you've really gotten all the old gunk out of your machine. I often wait several hours or even overnight to test the action after flushing before I re-attach body panels, etc.

If you can acquire a small plastic oiler (see https://boffosocko.com/2024/08/11/adding-to-my-typewriter-toolset/) it can help to minimize the amounts of solvent you're using and the flexible tip will allow you to not only direct the flow of solvent, but create some fluid pressure when you squeeze the bottle.

(Naturally use your degreaser in a well-ventilated space away from open flames and sparks...)

u/lodger238 at https://reddit.com/r/typewriters/comments/1hslx56/huh_i_thought_wd40_was_horrible_as_a_lubricant/<br /> Agree completely and to further the point; typewriters were manufactured with low tolerance in many areas just so they wouldn't need lubricating.

Symptom: Ghosting lines overlaying typed text:

This is assuredly not a type slug cleaning issue and the secret is that the loops in the letters like "a", "e", "o", etc. are clear. The lines are caused by the paper not being held to the platen, so when the slug hits, you're getting ink from the other part of the slug transferring to the paper. The remedy is to tuck the paper underneath the paper bale and rollers.

If one still sees issues after this then check your manual to ensure that the ribbon is properly threaded followed by a check that the ribbon vibrator isn't bent too far away from the typing point and too close to the platen and causing the ribbon to rub against the paper.

Pelicram's Shellac Rescue Formula aka The Cowboy's Delight.

This will help bring back a deeper black color shellaced panels which have been yellowed and damaged by UV over the years. With enough elbow grease it will remove the old shellac completely but it takes a very long time and you're likely to damage any decals present on the panel. In most cases the procedure described below will be sufficient to restore the appearance to an acceptable level.

The recipe: - 70% Light machine oil. - 30% IPA (Isopropyl Alcohol) or White/Mineral Spirits.

Ideally use an oil that is dissolved into the IPA/Mineral Spirits, if they settle into separate layers make sure you shake the mixture thoroughly before applying.

Mix the oil and solvent in something like a dropper bottle or similar vessel for convenient application.

• Clean part with Fulgentin (Or general purpose cleaner of your choice) and wipe dry.
• Apply oil/ipa mix to part and rub in lightly with clean microfiber cloth or shop towel. Use plenty of the mix, it should not feel dry.
• Wipe with microfiber cloth after 15 minutes to get rid of any excess.
• Do not apply any kind of wax (like Renessaince Wax) afterwards, from my testing it will bring back the haziness.

Cleaning Type Slugs Fast ! Removing Clogged Dirty Ink Typewriter Service How to Shine Those Faces by [[Phoenix Typewriter]]

Duane cleans type slugs by draping the typewriter with cloths and then using a metal bristle brush and lacquer thinner. Small picks or an X-Acto knife can help to remove gunk from the interiors of the closed letters.

He also uses tape to cover up the red paint on the word "De Luxe" so that the lacquer thinner doesn't damage it.

He finishes off with a small shot of Nu-trol, which is a degreaser with some lubrication, and then follows up with a shot of compressed air to thin it out.

The slugs are the metal pieces at the ends of the assemblies that start at the tops of the keys and go through the key levers attach to the segment (the semi-circular metal comb-like part in the "basket") via the typebars. The slugs are the ones that have the backward characters on them and when they hit the ribbon cause the letters to be applied to the paper. Over time the small loops of the characters can get filled with dust, dirt, ink, and bits of ribbon and as a result the type on your page isn't as crisp and good looking as you'd like.

Here's a handful of videos with a variety of methods for cleaning one's slugs: - https://www.youtube.com/watch?v=2s8tE6P0YMQ - https://www.youtube.com/watch?v=SgSAS45WGI0 - https://www.youtube.com/watch?v=jKGipBLA5Eo

You'll notice that for the day-to-day cleaning that people are using kneadable erasers, silly putty, or products like Bergeon Rodico 6033-1 as cleaning compounds for pulling ink and dust out quickly.

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.

reply to u/MirageAnne at https://reddit.com/r/typewriters/comments/1mgmwkq/remington_rand_17/

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.

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.

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.

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.

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!

Suggestion to use "barbecue igniting fluid"! 🤣

for - quote - waking up - growing up - showing up - cleaning up - f-ing up - John Churchill

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.

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.

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.

Typewriter 101: THE CLEANING GUIDE! by [[Just My Typewriter]]

A solid primer for cleaning typewriters

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.

Wiping dirty plastic typewriter keys with a soft cloth and then waxing/buffing them can bring them back to life.

Cleans them but probably doesn't repair them.

He still seems iffy about the value of using WD-40 on crinkle cut finish, primarily because of the smell.

Others use brass bristle brushes for applying the WD-40 instead of nylon brushes.

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.

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.

Imagine having unnecessary and wrong data in your document, you would most likely have to experience the concept of time demarcation -- the reluctance in going through every single row and column to eliminate these "garbage data". 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. I personally use dplyr and ggplot2 when I deal with data cleaning, and they are extremely helpful. WIthout these packages' existence, I have no idea when I will be able to reach the final step of data visualization.

If your garden is well maintained, you are more likely to spend time there. A well-kept garden can create an overwhelming feeling of calm and order even when you’re just looking out at it. This is similar to having a clean, neat and tidy house. Feeling better is good. Furthermore, a beautiful and healthy garden will truly enhance the appearance of your property. To accomplish that, there are a variety of steps that need to be taken.

When you engage a professional gardening cleaning service, they ensure that your garden's lawn and hedges are properly mowed and manicured.
