What to clean old lap sealant with besides denatured alcohol

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?

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.

Yes, that paint thinner would be mineral spirits.

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.

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.
