303 Products RV Wash & Seal - Clean, Streak-Free Finish, pH Neutral with High Foaming Formula, Provides A Deep Gloss Finish on RVs, Campers, Pop-ups, and Motorhomes, 1 Gallon (30240)

I did a lot of research on what to wash our camper with because it needed a total wash from the roof to the bottom. and if you have ever washed one by hand you know its an all day job, but if the product you use works its worth it & this one is! I used a soft brush a wash cloth and the water hose. & from the very first wipe you could see such a difference. It took all of the road grime off & smelled amazing. & tons of suds. The quality was great, it took only 1oz to 5 gallons of water. Very effective and not sticky. Rinsed easily and left a nice shine.

Cleaned my Rv beautify Loved it so much Cleaned my Truck and a trailer

Works like a charm. Got rid of stains and light tar and road grime. Then, left a beautiful mirror finish. Easy peasy. Love it and will be a repeat customer when this bottle is empty!

This does a nice job cleaning and leaving a nice shine. I don't really know how much "sealing" it does. Attached pics show before, during, after. Foams up nicely, I used an Astro AI foam cannon (do recommend) with 1 oz of the 303, allowed to dwell for a minute or so to get a pre-clean, then used a DIY Detail safe brush (do recommend) and 5-gallon bucket with 2 oz of the 303 to add lubrication for the contact cleaning. All done with my Sunjoe pressure washer (don't recommend, but it works). End result is a respectable appearance with about as little effort as you can expect from a task as daunting as washing a 40' rolling building. The after shows a distinct increase in gloss somewhat picked up on the pics, but in person it is significantly better.

Really good product. Like a Wash/Wax all in one. Made my Fiberglass Travel trailer look new again. Even renews the oxidized Black plastic a little. Only issue is it leaked all over the box in shipping. Need to tape the lid before shipping.
