Rubbing alcohol has a bunch of water in it-for some reason I am thinking 30 percent. The alcohol is isopropol. I use this all the time to clean up epoxy and it works fine. It is a little easier on the hands.

As an alternative, I would suggest that you try methyl alcohol, or methanol. It is also called "wood alcohol" because it can be produced by chemical reaction with wood. I use this sometimes, but if it gets on my hands, it really dries things out. There are times you will want to use methanol instead of rubbing alcohol. I am not sure why you would need to use denatured ethyl alcohol.

You can purchase methyl alcohol at any paint store.

I hope this helps.
