I know this is computer printer forum, but I cannot find a group for
typewriters, so am posting here.
My Olivetti typewriter's keys are filled with junk in the "e's",
"o's", "p's", etc.
what is the best method for cleaning the keys & removing this junk?
The grooves are usually painted inside with a good white paint. I use a
toothpick to wipe out the gross gunk, then I use isopropyl alcohol to
wipe down all key surfaces and the typewriter surfaces as well. Any
residual gunk can be cleared with a bit of tissue wrapped around the
toothpick, dipped i the alcohol, and used to clear gunk. Do not pry the
white pant, else it might come out too!
I might have misunderstood you, perhaps you mean the typeface of the
swinging printer key letters. These are cleaned similarly; with a
toothpick, using isopropyl alcohol, at least 70% and preferably 90%. An
alternative if paint thinner or lacquer thinner. The latter can dissolve
the paint on the enclosure surfaces and the touch keys, so use
sparingly. 90% isopropyl alcohol is the mst efficient solvent. You have
to partially depress the touch key so the the printhead key is exposed
half way to the platen. use yur other hand to hold it there , then with
the forst hand, maneuver the toothpick. A toothbrush also works well.
Scrub and pick out the letter printing key head depressions until
satisfied.
