303 Products RV Wash & Seal Concentrate 1 Gallon – Hydrophobic, pH-Neutral RV & Boat Shampoo

303 RV Wash & Seal is a concentrated RV shampoo that cleans dirt and grime while leaving a built-in hydrophobic sealant for faster drying and glossy protection.

Designed for boats, campers and recreational vehicles, this 1-gallon formula combines high-foaming cleaning power with a non-abrasive, pH-neutral finish that won’t strip existing waxes or coatings. Its hydrophobic adhesive encourages water to sheet off painted and gelcoat surfaces, reducing spotting and speeding up drying after rinsing. The product also includes UV-resistant elements to help guard painted finishes against sun fade and deterioration.

How does this cleaner remove dirt without harming existing coatings?

The wash uses a pH-neutral, non-abrasive surfactant system that lifts road grime, bugs and organic residues without attacking waxes, sealants or paint finishes. High-foam action suspends soils so rinsing removes contaminants rather than redistributing them across the surface. Follow the dilution directions for best results.

• Concentrated: 1 ounce per 5 gallons of water for economical use
• High-foaming formula lifts and suspends dirt for easier rinsing
• pH-neutral to preserve existing wax and protective layers
• Gentle on polymer and painted surfaces, safe for gelcoat

Will this product help reduce water spots and drying time?

Yes — the built-in hydrophobic sealant encourages water to bead and sheet off smooth surfaces, which minimizes standing droplets that cause spotting. When paired with a prompt rinse and dry, you’ll finish faster and with fewer water marks. The glossy residue left behind also supports easier future cleanings.

• Hydrophobic adhesive promotes rapid sheeting of rinse water
• Leaves a glossy finish that helps repel water and grime between washes
• Reduces towel labor by minimizing stubborn water spots
• Works well when dried immediately with a clean microfiber towel

How does this product protect against sun and environmental exposure?

Alongside cleansing and water-shedding benefits, the formulation contains UV-stable components designed to help slow paint and gelcoat fade. Regular use preserves the surface’s appearance and supports long-term maintenance routines without heavy polishing. It’s intended as part of routine care, not a substitute for dedicated paint restorers.

• Includes UV-protective ingredients to help reduce sun-related fading
• Safe for repeated use as a maintenance wash
• Helps maintain surface gloss between deeper detailing sessions
• Compatible with waxes and other protective coatings

How do I use the 1-gallon concentrate for best results?

Mix one ounce of product into five gallons of clean water, gently apply with a soft wash mitt or sponge, then rinse thoroughly. Immediately dry the surface with a clean towel to lock in the hydrophobic benefit and avoid spotting. For heavily soiled areas, repeat spot-cleaning before rinsing.

• Mix ratio: 1 ounce per 5 gallons of water
• Apply gently with a wash mitt; avoid abrasive brushes
• Rinse thoroughly and dry immediately with a clean towel
• Store in original container; product best within two years of packaging

Who this is for: 303 RV Wash & Seal is aimed at RV, camper, trailer and boat owners who want an efficient, concentrated wash that cleans gently while adding a water-repellent finish. It works well for seasonal campers preparing for storage, frequent road trippers who need quick, effective maintenance between outings, and anyone seeking a rinse-and-dry routine that reduces water spotting and preserves surface appearance.
