Sarah treated the internal felt of her typewriter by spraying it down with white distilled vinegar. This kills any living molds, etc. Vodka is also good for removing scents on typewriters (and vintage bags).
The variable line spacer is inside the platen of a Hermes 3000.
The carriage of the H3K comes off with the removal of two bolts.
For rust removal Sarah starts with a wire brush then does PB Blaster for more.
Replace rusted springs.
Fingernail polish for a H3K:<br /> - Sally Hansen Insta-Dry line "Time is Money" (discontinued?) - Expressie Essie quick dry "In the Modem" (closest in her opinion) - Sinful Colors Eucalypta - Blank Beauty (color match to Hermes Ambassador) - Orly (meh, too green)
The case doesn't remove intuitively.
