Protect All’s Rubber Roof Cleaner is formulated to dissolve roof dirt and chalk and to
reduce the time and effort it takes to wash a motorhome’s roof. The company says the
cleaner helps to eliminate messy runoff and conserves water because the mop soaks up the
grimy residue and can be squeezed into a bucket rather than running down the sides of the
rig. The cleaner is biodegradable, nontoxic, nonabrasive, safe for all rubber-roof
materials and ideal for RV parks where washing and rinsing are prohibited, according to the
