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.

Follow up:

As recommend by so many, I got me a bottle
of "cleaning ammonia" from wally world. I tried
a bit on my nasty looking space bar. Oh boy did
it look pretty afterwards! Worked like a charm.

But, the smell almost made my head spin. I will
take the keyboard OUTSIDE, probably over the
weekend, and finish off the rest of the keys.

Thank you all for the help!

Yes, use in a WELL ventilated area, I once took a breath out of a bottle
labelled paint thinners, Some asshole in our cleaning staff had filled
it with pure ammonia without relabeling it, Well I nearly passed out and
couldn't breath for a couple minutes, so be careful.

That's one of the things they warn you about in chem class.

One day, one of the professors dropped by during labs, and
gave us a demo of this technique. You wave your hand over the
test tube, to help dilute the vapor so it isn't quite as
concentrated.

This is fine, if you know what was put in the tube in the
first place. Not so clever with a complete unknown.
