It may depend on the pharmacy, and methanol is more likely to be in the

the States, "methylated spirit" for a variety of purpose is commonly
available in the UK and most of Europe -- it's a mixture of ethanol and
methanol (plus dye). The point, however, is that methanol is a better
solvent for felt-tip and ballpoint pen inks than isopropanol is, and
that's what the original reference was about, IIRC.
For glue residue (incl. duct tape), though, what we call "white spirit"
or "turpentine substitute" (not to be confused with cellulose paint
thinner) in the UK, is better than any of the common alcohols.
None of the above will have any effect on most plastics, unlike
toluene, MEK, acetone, ..., all of which are solvents for many plastics
(in fact, for most non-waxy plastics, which leaves little but polythene
and PTFE).

How many people keep something as nasty as MEK in their house?
Generally if your trying to disolve something then pick a solvent in the
same family as the ink is made out of. like disolves like is a general rule.

MEK has all but been banned in the US and is just about impossible for an
individual to obtain. Besides it EATS plastic!

Yes, but at one point in time not that long ago people used to clean their
hands with the stuff (guess thats why we live longer now). I am afraid to
find out what solvents and chemicals my father has in the garage these days.
Anyway the problem with computers is that the texture that makes markers and
sticky stuff so hard to clean off the plastic is easily damaged with
solvents and ruins the look of the part. MEK would actually disolve common
plastics (and has been used to do just that).

yes you can still get it but you have go to a chemical co. It's not
readily available the way that alcohol, mineral spirits, etc are.

I don't know if it's full strength or not..... what would it be thinned
with? I'll look too. I'm curiuos now. I need to go to Lowes any way
to buy a dust pan and broom for the basement.
