Hello,
I would appreciate some recommendations for cleaning products
to use on a couple of HP 41 C's I am trying to bring back
to life.
One of them is VERY grungy, with a lot of graphite-like
stuff all over it. One of the battery terminals is also
rather green, and I guess I'll try the pencil eraser method
on it. Their cases are also fairly dirty, though the foam
seems in good shape. Can one wash those?
In looking over the forum archive, I've run across
people recommending/using:
SNAP plastic cleaner
diluted Simple Green
I have personally used ethanol and Q tips in the past, which
worked well (denatured alcohol), but I am trying to do a
proper restoration effort, so I am going about this slowly.
Any guidance will be much appreciated.
Happy New Year,
Ion Abraham
