Hi All,

I have a old off white keyboard that adore in
my shop. The keys are starting to look a bit
nasty.

I have tried rubbing alcohol and vinegar and
nothing seems to clean it up.

Any words of wisdom.

On a related matter, if the keyboard or any other electric device like
a toaster or heater has had greasy stuff, or coffee, or strawberry jam
spilt into it, then wash it with a soft brush and flush with
methylated spirit, shake it dry and then leave it in the sun (or lab
oven @ 30degC) until thoroughly dry. You may need 70% methylated
spirit.
Works for pocket calculators too.
