91% isopropyle Alcohal?

[AyashiKaibutsu]

I have a bottle of this and wondering if it's good or should I seek out 99%?

I use 91% all the time for core & HS cleaning. Make sure and leave the cap on. If not, the alcohol can evaporate, leaving you with less than 91% concentration.

Been using the same bottle of 91% I got from Target for the last 4 years, works great.

I use pure asitone, works quite well.

Acetone? As in fingernail polish remover?

I just bought some 70% isopropyl from Big Lots for $.49/pint. The balance 30% is purified water. I can live with that.

We only roll with 91%

It's what the makers of Arctic Silver recommend.
