Thetford Premium RV Rubber Roof Cleaner 64 oz — Non‑Toxic, Non‑Abrasive EPDM Conditioner

Keep your RV roof performing and looking its best without harsh chemicals. This ready‑to‑use 64 oz formula cleans and helps condition EPDM rubber roofs, dissolving chalky residue and organic soils so you can rinse them away. Thetford engineered the product to be biodegradable and gentle, making it suitable for routine maintenance and seasonal deep cleaning alike.

How do I use Thetford Rubber Roof Cleaner safely and effectively?

Follow a simple three‑step process: remove loose debris, treat a small area, then rinse and let air dry. Work in sections to prevent the cleaner from drying on the surface, and always avoid abrasive scrubbing that could damage EPDM.

• Sweep off dust and loose material starting at the front and moving toward the ladder.
• Spray a 2–3 sq. ft. area, agitate with a sponge mop or soft bristle brush in circular motions.
• Rinse fully and allow the roof to air dry before walking on it; wipe any runoff on sidewalls carefully to avoid white streaks.

Will this cleaner damage my EPDM rubber roof or RV finish?

Thetford’s formula is non‑abrasive and formulated specifically for EPDM rubber, so it won’t strip or roughen the roof when used as directed. Because the product lifts chalk and residue, runoff can leave temporary white streaks on painted surfaces if not wiped promptly.

• Safe on EPDM when used per instructions and rinsed thoroughly.
• Biodegradable and non‑toxic—no harsh acids or solvents.
• Carefully clean residue from sidewalls to prevent streaking on paint.

What kinds of stains and buildup does it remove?

The cleaner targets common roof contaminants like oxidation, chalking from UV exposure, bird droppings, and accumulated dirt and grime. It acts as a degreaser to loosen stubborn deposits so they rinse away without aggressive scrubbing.

• Removes oxidation and chalk residue caused by sun exposure.
• Loosens bird droppings, pollen, road film, and general grime.
• Works as a degreaser to break down oily spots and buildup.

How does regular use affect my roof’s lifespan?

Routine cleaning with a gentle, conditioning cleaner helps prevent long‑term staining and keeps the rubber surface flexible by removing materials that accelerate aging. While no cleaner can stop UV degradation, preventing buildup reduces stress on seams and coatings.

• Removes contaminants that can cause premature wear.
• Conditions EPDM to help maintain flexibility and appearance.
• Supports preventative maintenance to extend service life when combined with other roof care practices.

Who is this for? RV owners, fleet managers, and professional detailers who need an effective, safe cleaning solution for EPDM rubber roofs will find this product useful. It’s especially suited to those who want a biodegradable, non‑toxic option that dissolves chalk and organic soils without abrasive chemicals.
