Working on a DM5010 multimeter it has a bunch of little square button
switches on the front panel, a few are sticky, should I try and clean
them or lubricate them ? And how with what ? I have it completely
apart they don't apear dirty, they are plastic, I beleive the same are
used on some later scopes. Thanks in advance for any wisdom on this
subject, Jon P.

Do not forget lubricant, it is amazing what a little bit of grease can do
for sliding. I am not sure what would be the best or recommended grease for
those switches, but I would try (thick) silicon grease, I do not think that
you can go very wrong with that choice. Spray silicone would not give you a
durable solution and there is a chance that vehicle in spray (solvent) can
attack plastic.
