Thetford Premium RV Rubber Roof Cleaner 64 oz — Non-Toxic, Non-Abrasive EPDM Detergent & Conditioner

Thetford Premium RV Rubber Roof Cleaner & Conditioner is a non-abrasive, biodegradable 64 oz formula designed to lift oxidation, bird droppings, and chalk from EPDM rubber RV roofs while conditioning the surface.

Keep your RV roof clean and protected without harsh chemicals. This concentrated detergent is formulated specifically for EPDM rubber roofs used on travel trailers, motorhomes, and fifth wheels. It removes embedded grime and chalking layers so the roof looks restored and is easier to maintain between deep cleanings.

How do I use this cleaner step-by-step?

Cleaning with Thetford is straightforward and organized into three practical steps to avoid damaging the roof membrane. Work in small sections, use soft tools, and rinse thoroughly to prevent residue streaking down the vehicle sides.

• Sweep loose dust and debris off the roof, beginning at the front and moving toward the ladder.
• Spray cleaner on a 2–3 sq ft section and agitate with a sponge mop or soft-bristle brush in circular motions.
• Rinse each cleaned section completely and let the roof air dry before walking on it or applying any protectant.

Will this product harm my EPDM rubber roof?

Thetford formulated this detergent to be non-abrasive and safe for EPDM membranes when used as directed. It won’t strip the roof’s surface when applied with soft tools and rinsed properly, but avoid harsh scrubbing or aggressive pads that could damage the material.

• Biodegradable and non-toxic formulation for safer use around RV components.
• No abrasive fillers that could scratch or wear rubber membranes.
• Avoid metal bristles or stiff pads; use sponge mops or soft brushes only.

What kinds of stains and buildup does it remove?

The active ingredients are designed to dissolve oxidation, chalk, and common organic debris found on roofs, such as bird droppings and road grime. For heavy or long-set stains, a second application and gentle brushing may be needed to fully lift the residue.

• Removes chalking from old or UV-exposed EPDM rubber.
• Breaks down bird droppings, light staining, and accumulated dirt.
• Helps reduce the appearance of black streaks when used regularly.

How do I prevent drip marks and white streaks on my RV sides?

Because EPDM can leave white streaks from runoff, take care to clean and wipe any drips before they dry on painted surfaces. Rinse thoroughly and immediately wipe residue from the vehicle sides with a sponge or rag to avoid visible streaking.

• Rinse each roof section completely before the cleaner runs down the sides.
• Keep a bucket and sponge handy to wipe any runoff from painted or metal panels.
• Allow the roof to air dry fully before walking on it or applying sealants.

Who is this for: Thetford Premium RV Rubber Roof Cleaner & Conditioner is intended for RV owners, fleet managers, and technicians who maintain EPDM rubber roofs and want an effective, non-abrasive cleaning solution. It’s a good choice for anyone aiming to remove oxidation and organic grime without harsh solvents—ideal for regular maintenance or seasonal deep cleans to extend roof appearance and serviceability.
