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...

Then ... neither he nor you read what the subject of this thread is about "what does fresh epdm look like?". Your wordy treatise on TPO cleaning also has nothing to do with the compatibility of the actual material being discussed here and acetone and as such is just noise or the proverbial "red herring".
Neither the OP nor anyone has identified his particular roof membrane as being an Alpha product nor has it been determined that it is for sure EPDM, TPO, or any other formulation, other than him referring in his original post to "icky grey / black chalk" when he cleaned the roof, which in itself suggests it is EPDM that unlike TPO does chalk naturally and when cleaned. Nonetheless, Alpha arguably supplies most roof membranes to US RV manufacturers and as detailed here the company manufactures EPDM, TPO, and what they call Alpha-Ply roof membrane. The cleaning instructions, entitled Cleaning and Maintaining the Alpha Systems Roof Membrane make no distinction between these three different roof membrane products ...
"DO NOT USE ACETONE, OR ANY OTHER PRODUCTS CONTAINING PETROLEUM DISTILLATES, ON THE ALPHA SYSTEMS ROOF MEMBRANE. USE OF THESE PRODUCTS WILL DAMAGE THE MEMBRANE."
Seems clear enough to me. :W
