Found it. I'll use a little more of the 70% in the mixture so I'm safely over the 60% threshold.Ok thanks. I have about a quarter bottle of 70% rubbing alcohol left and also found some 50% in a bottle. Didn't know if i could mix the two to make it last longer and keep the alcohol content above 60% and mix it along with my aloe.
