I get my denatured alcohol at the hardware store. Home Depot'll do too.

| Should. Goes by various names: "methanol," "methyl alcohol," etc. Use a
search engine to find other equivalents. You definitely want the pure
stuff -- no additives of any kind (otherwise, you could just use gas-line
antifreeze, which is primarily methyl alcohol). You can also substitute 99%
isopropanol (which, in Canada anyways, is available at pharmacies). The 70%
solution (the other 30 0s either mostly or exclusively water) is sometimes
called "rubbing alcohol," but I don't recommend it in case some gets into
the lens (though to be fair, you'd have the same problem with Windex;
moistening the cleaning pad first and then cleaning the lens surface while
holding the lens upside-down is the best strategy). In any case,
isopropanol isn't quite as good at dissolving grease/grime as methanol, but
if it's all you've got, it's most likely more than good enough.

which, despite its high-falutin' name, is nothing more than pure methanol.
This stuff's made in the USA by Photographic Solutions, Inc., Buzzards Bay,
MA 02532, phone number (508) 759-2322. The claim to fame of this stuff is
that it *is* a system -- comes with special pads (called PEC*PADS) that are
ultra-clean (supposedly 99.999 0.000000ree of impurities). The pads are
probably
more important than the methanol, and can be purchased separately. I like
the pads. PSI's methanol is probably way over-priced...
