What does fresh epdm look like?
Spring is here and I took the first opportunity to use some Dicor rubber roof cleaner that the previous owner of my trailer threw in last summer. Well, it worked really well at taking all that icky...

There are only a couple of manufacturers of rubber roof membrane in the US, Alpha Systems likely being the largest, so it only seems logical to me that one would first check any documentation that would identify just which membrane is on the trailer in question, then call that manufacturer with any concerns. FWIW, Alpha System's Cleaning Instructions specifically warn against using acetone. :W
