With our recommended 303 products, washing an RV doesn’t have to be an all-day affair.

Whatever your destination, your RV delivers memorable experiences with those who are special in your life.

Washing Your RV

Periodic washing is ideal, particularly if you are traveling routes that get dusty or muddy. The outside of your RV faces repeated assaults by an array of harmful substances, including:

Dust, dirt and grime

To protect your investment, periodic washing is highly recommended. Avoid using regular dish soap because it can strip away protective coatings. Instead, use 303 Ultra-Concentrated Car Wash.

RV manufacturer Jayco offers these tips for washing the exterior of your RV.


  • Avoid washing in direct sunlight
  • Spray with clean water to remove dust and dirt
  • Prepare a mild car wash solution
  • Starting at the top, use a 303 Car Wash Mitt to wash your RV
  • Rinse liberally with clean water
  • Wipe dry with an appropriate cloth or towel


  • Use very hot water
  • Let a pressure washer nozzle get closer than 16 inches to the surface
  • Point a pressure washer at door and window seals or around appliance vents

Avoid abrasive compounds and anything that leaves a filmy residue behind.

Always use pressure washers with caution. Go light on vulnerable areas, like those travel decals on the rear of your RV. You always want to strike a balance between dirt removal and protecting the finish.

Bug residue, road tar and other contaminants

Road tar, bug residue, bird droppings and tree sap stubbornly adhere to exterior Over time, these contaminants can stain or even etch the outside of your RV. Avoid the temptation to use gasoline or petroleum-based solvents to get rid of these surface contaminants. Instead, use a product formulated for the task.

Oxidation and other UV damage

The body of an RV is typically made of fiberglass because it is lightweight, durable and resilient. Such surfaces are typically covered with a resin-based gel coat. Over time, oxidation often causes gel coats to get yellow or hazy. Use 303 Aerospace Protectant to remove gel coat oxidation and inhibit future damage caused by the sun’s ultraviolet rays.

Tire browning

Apply 303 Tire and Rubber Cleaner to your tires and other rubber surfaces. It cleans up tire browning, a common challenge given the conditions RV tires endure.

RV tires suffer from browning just like any other tire.

Cleaning the roof

EPDM rubber membrane roofs are UV and leak-resistant. EPDM roofs, petroleum distillates and harsh abrasives do not mix! You may void your warranty if you use the wrong product on your RV’s EPDM roof. Petroleum distillates may actually loosen the adhesives holding the rubber membrane in place. Instead, use 303 Aerospace Protectant. The UV-resistant formulation prevents fading and cracking. It also restores lost color while imparting a pleasing matte finish.

Protecting Your RV

Once your RV is nice and clean, you’ll want to treat exterior and interior surfaces to further protect your investment.


303 Touchless Sealant is a new protectant with special qualities. Enjoy a glossy, UV-resistant exterior finish that can last for months. It is safe for use on fiberglass gel coat, painted surfaces, wheels and windshields. 303 Automotive Speed Detailer inhibits fading, reduces streaking and protects against light scratches.

Restore that “like-new” look to your tires with Tire Balm & Protectant. Apply extra coats for a shinier look. Reduce the chance of fading, cracking and dry rot with this UV-resistant formulation.


Many RVs have leather and/or vinyl surfaces. Use 303 Automotive Leather 3-in-1 Complete Care to clean and protect seats, cushions and other surfaces. For other interior surfaces, use 303 Multi-Surface Cleaner.

Wherever you find yourself during this season of adventure, 303 Products has you covered! Our premium cleaners and protectants help you care for RVs and other vehicles of all kinds.

  • I can’t find the product :Rubber Seal Prtotector

    • We’d recommend going for our 303 Protectant

  • Hi, shouldn’t we expect water beading from from rain after application of 303 Aerospace Protectant? The RV is a 2019 class A with a fiberglass roof, freshly washed 2 times and the 303 Aerospace Protectant applied with cloth applicator and buffed off. We only needed to use 1/2 quart to do the whole 28′ roof.

    Thanks for the help.

    • Aerospace Protectant is a great choice for UV protection but when it comes to Hydrophobicity we’d recommend our 303 Touchless Sealant

  • Thanks for the information. I was led to understand that as the product wore out there would be less beading action showing a need for another application.

    So as to the amount used, a pint would be a normal amount to use on a 28′ fiberglass RV roof?

    Thanks again and have a great day.
