Found out last night you cant buy denatured alcohol anymore in my area. Even amazon wont ship it.

Acetone seems so strong. Go with IPA instead? Or maybe a cleaner like SPRAY 9?

Whoa! Go to the nearest pharmacy and buy isopropyl alcohol. Get the 91% not the 70% alcohol. Denatured (ie, 95% ethyl alcohol 5% gasoline) even if available is a bad idea for rubber roofs anyway. Every pharmacy carries isopropyl alcohol. It is sold as rubbing alcohol and for sterilization of medical equipment.

Dicor has a couple videos on YouTube. They recommended denatured alcohol for final prep.

I love the stuff for applying silicone caulking. Guess will have to switch over to IPA.

Paint thinner does a better job of cleaning and removing old caulking. As a final step before recoating, I do use 91% alcohol.

Yes, that paint thinner would be mineral spirits.

The instructions say to use mineral spirits and it does a good job without breaking it down. You can then go right over the area with more Dicor.

I have used Denatured Alcohol and Mineral Spirits. I prefer Mineral Spirits; I feel it cleaned better with less effort.

Cool deal. Not a fan of mineral spirits. Trying to think up a good reason why. I want to say it leaves a film behind. I have a full can of the stuff in my truck.

Nonsense. Amazon sells and ships featured alcohol.
