95% is a very good figure. I actually use the NON-denatured

How about the drinking stuff? (95% "grain" alcohol).

Here I can by a "fifth" (750ml) for less than 250ml of 70%
Isopropyl.

Well, that's ethanol, which should also work fine, so long as
you
don't mind the 5% water.

I use medical or denatured alcohol as a general-purpose cleaning
solution. When I need stronger stuff, such as on cruds of old and
hardened flux or when there's simply lots of it, I use automobile
paint thinner. Wiping with a piece of cloth or cotton wool is
usually enough and I rarely need to scrub with a brush.

The thinner can dissolve some plastics though. So some care is
needed, as is good ventilation. It looks and feels somewhat oily
but dries very quickly. A one-liter can costs about $3 US here.
