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!

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.

How to Clean a Typewriter (Apartment Friendly Guide!) by [[Just My Typewriter]]

Alan Thorpe cleans his Perkins Braillers in a paraffin bath.

It's the story of convenience seen everywhere. Could you clean your machine with household items like isopropyl alcohol and a Q-tip? Sure. Are mineral spirits better solvents in combination with compressed air for doing this? Definitely.

People will tend toward the least common denominator for doing what is cheapest and easiest for their time, location, expediency, availability of materials, level of knowledge, and experience.

The trade off may be long term life of the typewriter with respect to risk of rust, corrosion, or other potential issues.

Suggestion to use "barbecue igniting fluid"! 🤣

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.

Olympia SG1 1953-72 cleaning (technical restoration)

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.

Typewriter 101

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.

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.

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.

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.
