Reddit reviews Liquid Wrench L512 Dry Lubricant with CERFLON - 11 oz.

For cleaning use Mineral Spirits. If the letters have a thick coating of ink use a small brass brush with mineral spirits. (odorless mineral spirits are available at every hardware store. It is the safer modern equivalent to Varisol.)

If I am correct and the Smith Corona has a sealed bottom. You want to take the bottom plate off to clean it. Using a dropper or Q-tips put little amounts on all the moving parts and then move them letting excess mineral spirits drip out the bottom. Repeat until the part is clean and moves freely. Wipe gunk off from all the none moving parts.

Traditionally only certain parts of the typewriter are lubricated with 10w machine oil. (Sewing machine oil.) Everyone including me use too much the first time. But even if you use the proper amount dust still sticks to it.


Use Liquid Wrench Teflon spray to lubricate all the moving parts. (It is cheaper to get it from an auto parts store or Wal-Mart.) It works as well as 10w oil and because it is dry dust doesn't stick to it. Spray everywhere, quickly wipe it off anywhere you don't want a coating of white dust.

I recommend the Liquid Wrench because it worked best of all the ones I tried. Do not use the Dupont Teflon spray because its "Patented Bonding," agent means it is much harder to clean from anywhere you don't want it.

I'm probably gonna die, but I use a quick blast of automotive brake parts cleaner to get my cams clean, dry them with compressed air, and apply Liquid Wrench Teflon spray lube. Seems to get the cams good and clean without scrubbing, and keeps things nice and smooth operating for a long time without attracting gunk.

You could try Liquid Wrench Dry Lubricant. I dont have any experience with it. But reading some Amazon reviews, it sounds like it would work.

I'm still experimenting with different lubricants and cleaning sprays but the best so far:

1. No spray cleaning or lubricant works as well as taking it apart, completely cleaning it and lubricating it. Dust gums up oil. If you can afford to pay a professional to clean and service your typewriter, do so, the difference in the action of the keys is phenomenal.
   
   
2. I bought a Super Silent with sticky keys off E-bay and fixed it with these two products. Mass Air Flow sensor cleaner, and Dry Lube. Use the spray cleaner to clean out as much gunk as you can and the the spray lube to get things slippery again. (It takes a couple of sprayings combined with moving everything you want lubricated.)
   
   Dry Lube is spray Teflon that does not attract dust. This solution worked but does not completely clean out all the dust or make the action like new.
   
   I am presently disassembling my Super Silent and after properly cleaning it, I will experiment with various oils, PTFE(Teflon), and wax/ceramic lubricants and compare how they affect the action of the keys.
   
   For all parts other than the keys I am already convinced that dry lube is a better solution than any oil because not only doesn't it attract dust but you can blow out any dust with compressed air.
