[quote name='Apossum']does it make a big difference? i'm using 90% rubbing, so i'm curious. I can't find 100% alcohol anywhere, maybe i'm not looking hard enough.[/QUOTE]
It shouldn't make that much of a difference, I don't think. The rubbing alcohol is what cleans it, so just as long as it is a strong solution of isopropyl alcohol, it should work.
But as someone else pointed out, if you really want to use 100% alcohol, you could buy some isopropyl alcohol. This is basically the same as rubbing alcohol, but is often more concentrated.
