Guys, just my 2 cents worth, but I have had VERY good luck using Armor All.  I use the wipes that come in a cylindrical container where you pull out one wipe at a time very similar to baby wipes.

 

I take one key at a time and thoroughly clean and polish the key.  I’ve used this procedure both on M28 gear and Kleinschmidt gear.  Now I’m going to try the same procedure on my newly acquired M33s.

Thanks for sharing, one time Randy took the whole lot of key tops put them in a plastic container for small parts, closed it tight and ran it through the dishwasher, that worked pretty well, as I recall., also. I am not sure what they were made of, nor what type keyboard they came off of.

 I like the idea of take a picture where everything is and soak over night too.

The keys are made of Tenite plastic or one of it's derivatives, made from cellulose.  It molds and mildews badly. In worse cases, the mold sort of corrodes the surface, and a mild abrasive polishing compound is needed to make the surface smooth again. Tenite aslo has a distinktive odor when heated or worked. I spent my youth in the place it was made, pieces of the plastic were easy to get, and the whole town had an "air" about it. Typists , however, liked the feel and "touch" of keys made of it, and it was quite popular for keyboards.

I know that others who have worked with these machines have encountered similar problems but I can't remember the exact products used to clean the keys and thought I would post about something I "discovered" while working on the machine I picked up a few weeks ago in Houston, TX.
