Alcohol question?

[ezdays]

Rubbing alcohol is diluted isopropyl alcohol and is naturally undrinkable. The most common is 70% alcohol and 30% water although you can find it diluted to 90%. Denatured alcohol is pure alcohol that comes from grain and intentionally has other things added to make it undrinkable. I would think that any of these would work but the denatured alcohol you get in the hardware store might be a bit more harsh than rubbing alcohol. The one big difference is the water content of rubbing alcohol, but in my opinion, it's more than adequate for our purposes. I use the 90% stuff and can get it just about anywhere although It runs about twice as much as the 70% stuff. I've even used it to wash brushes out that have hardened because I didn't wash them out while the acrylic paint was still wet.
