303 Products RV Wash & Seal 1 Gallon — Concentrated Hydrophobic RV Cleaner with UV Protection

303 RV Wash & Seal is a concentrated cleaner and built-in hydrophobic sealant engineered to remove road grime and leave RV exteriors streak-free with a water-shedding glossy finish.

Designed for motorhomes, travel trailers, and campers, this one-gallon formula mixes with water to deliver a high-foaming, pH-balanced wash that cleans without stripping existing wax or coatings. While it lifts dirt and road film, the product also deposits a durable seal that helps water bead and run off, reducing drying time and minimizing water spots. It includes UV-protective components to help slow down sun-driven dulling of paint, gelcoat, and decals so your rig looks maintained between trips.

How concentrated is this cleaner and how do I mix it?

303 RV Wash & Seal is formulated to stretch—just a small amount goes a long way. Follow the simple dilution ratio to get optimal cleaning power without waste.

• Recommended mix: 1 ounce of product per 5 gallons of water.
• Use a bucket, foam cannon, or portable sprayer depending on your setup.
• Apply with a soft wash mitt or foam applicator to avoid scratching surfaces.

Will it remove dirt without harming wax, decals, or protective coatings?

The wash uses a non-abrasive, pH-neutral formulation so it cleans effectively while preserving existing protective layers. It’s safe for painted surfaces, gelcoat, vinyl graphics, and clear coat finishes when used as directed.

• Non-abrasive ingredients won’t strip wax or factory-applied sealants.
• Safe for vinyl decals and exterior trim when rinsed properly.
• Rinse and dry immediately to avoid spotting and streaking.

How does the built-in sealant improve drying and long-term appearance?

The sealant deposits a hydrophobic layer as you wash, encouraging water to sheet off rather than cling. That sheeting action shortens drying time, reduces water spots, and leaves a visible gloss that maintains the vehicle’s curb appeal between more intensive detailing jobs.

• Hydrophobic adhesive causes water to bead and run off surfaces.
• Leaves a glossy finish that enhances color depth and shine.
• Contains UV-resisting agents to help reduce paint and coating fade.

What is the recommended process for best results on an RV?

To get the safest, most effective clean, work systematically from top to bottom using the dilution guideline and finish with a thorough rinse and immediate drying. Proper technique preserves protective layers and avoids re-depositing contaminants.

• Mix dilution: 1 ounce per 5 gallons of water in a bucket or foam system.
• Wash roof and upper surfaces first, then lower panels to avoid re-soiling.
• Rinse completely and dry with a microfiber towel or chamois to prevent spots.

Who this is for: 303 RV Wash & Seal is ideal for RV owners, full-time travelers, and weekend campers who want an easy, concentrated wash that cleans thoroughly while adding a protective, hydrophobic finish. It suits professional detailers and DIY enthusiasts who need a product that preserves wax and coatings and helps protect paint and gelcoat from sun exposure. Keep a gallon in your maintenance kit for seasonal cleanups and pre-trip detailing to keep your RV looking cared-for on the road.
