Is denatured ethyl rubbing alcohol really safe on plastic? I wouldn't think so. It's often denatured with acetone!

I will play it safe and stick with isopropyl alcohol. -Mike On Fri, Mar 4, 2011 at 10:32 PM, David Ross <[email protected]> wrote: > First, someone pointed out off-list that "rubbing alcohol" is not good >> stuff or this, and he's right.
