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.

This stuff is amazing.. cleaned all the black streaks and dirt straight off.. 5 stars, highly recommend it, I won't be buying anything else except this from now one

This stuff worked great! I hadn’t washed my trailer in a long time because it really wasn’t that bad but it was starting to get those dark streaks that you could visibly see from the street.

I mixed a few ounces of it with water in a 5 gallon bucket and used a long handled non bristle. I just slapped the wall with it and rubbed back and forth and easily wiped all the black away. No elbow grease and minimal effort.

Im actually kind of impressed.

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.

I put this on with a foam cannon on my power washer and the scrubbed with a brush and it worked perfectly. What a shine.

Great RV wash. We have a 5-year-old travel trailer that sits outside and gets gray colored spots all over it over time. We bought this and it removed all the spotting with minimal scrubbing; we used a soft car brush that extended so we could work from the ground. It leaves a streak free shine on the camper also and we have hard water. We did not have any dark colored staining/streaks so I don't know how well it would do on that. It has a nice smell, kind of like bubble gum. It took us about 1.5 hours to do our 33' camper working with one person scrubbing and one hosing off the siding. We added 6 ounces to a five-gallon bucket of water as directed, we did not have to add any more than that. Very happy with how this wash works and especially the streak free shine when done.

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.

Love this product. Lasts very well and great cleaner.
