Manufacturers mostly use unleaded gasoline to clean the seams of EPDM roofing materials. But you need to clean any dirt brushed or power washed away before cleaning the underlying EPDM with solvent cleaner.

I would like very much to see any reference to a manufacturer of EPDM or TPO that recommends using gasoline to clean their roofing material.

I would like to see ANY reference to using a highly flammable gasoline to doing any type work on an RV. BTW, NOBODY uses Gasoline to clean a roof EPDM or otherwise. Doug
