Biokleen M02409 RV Roof Cleaner and Protectant - Gallon

They should have sent a poet. I should have taken pictures! This stuff does an amazing job on cleaning the roof, but more amazing was how white my sealant was after just a few brushes. This literally made my roof look better than when we got it. Really impressed with this product. I didn't have any issues with it leaving a residue on the sides of my camper. I did wet the sides first, and after cleaning the roof washed and waxed the aluminum siding with a different product. So far 2 months after cleaning I've yet to have black streaks form again because ALL the crud that causes them has been washed away. Highly recommend!

Well I was optimistic about how it would work but as I got a new to me 5th wheel last year (2018 forest River) and previous owners kept reverting in great shape but didn’t clean the roof I knew I needed to get a good cleaning on it.My precious trailer I used a household detergent like simple green or something and it worked pretty good before I coated it with a roll on Henry’s coating, but I wasn’t doing that here.Moving along. Per directions they weren’t amazingly clear on how to apply the product or dillute it but as any company they always state more product than you really need so you come back to buy more, let me tell you this stuff works with jusr a little elbow grease and goes a LONG WAY!!!!!I mixed this product in a total of 1 gallon pressure sprayer, this allowed me the control of spraying on small amounts and cover the entire roof sections with ease. The pressure sprayer I’m talking about is the $15-20 HDX brand one at the orange big box store.ApplicationWet the trailer sides fullyWet the roof area to be cleaned, we did about 6’ at a time across the trailerLet sit for a couple minutesUse a soft scrubbing brush we put some elbow grease in, each section was 7-10 mins start to finishAfter scrub we let it sit another min or two then rinsed offWe hoses down the sides of the trailer as we went along tooAfter roof was done we sprayed entire trailer down very well and let dry a bit.About 2 hours later we washed the trailer with chemical guys brand extreme foaming cleaner to get any remaining stuff off and also clean the trailer too.So overall pro tip!Buy a pressure sprayer (think same thing for weeds)Use a 1:3 ratio or even 1:4Let sit 5 or so mins before scrubbingScrub with soft brush or lightly with firmer brushLet sit a couple mins after scrubbingRinse off liberallyRinse sides of trailer immediately after each section.The last part is critical as this stuff WILL streak the side of the trailer If not rinsed off.1 gallon is enough to allow me to do the trailer at least 8-10x before having to buy another gallon again. I’m going to do it again in a week or so to get anymore dirt off and prior to me taking a couple days to wash, wax and buff the entire trailer.Just click buy!

This was the best product I could find after extensive research. It cleaned my RV roof really well, and I have to take it on their word that the UV protection (SPF 70?) is as stated for the product, which I was very interested in. Just follow the directions: Wash small areas at a time and keep the RV sides wetted down to protect against black streaking caused by the gunk being washed off the roof.I inquired about whether it could be used on the gel-coat walls of the RV as well. They simply said it wasn't made for that, but didn't elaborate. My take on that is that it certainly could be, but I suspect that they have other products in that product line for that that they would rather have you use. I think it would work great and have these benefits for me: 1) I wouldn't have to be so careful to avoid black streaks from the roof, as it does a great job of removing them, based on my tests; and 2) It may avoid having to use another product (like Aerospace 303) for the walls to get anything close to the same UV protection - time will tell.

This got my roof clean for the winter. It worked well but it needed a lot more brushing than I expected. Maybe I didn't let it set long enough but it worked better when I switched to a stiffer bristled brush than the softer one I started with. As far as streaks, where I wet the camper down first there were no streaks, but definitely streaked in the spots where I forgot.

I had seen where someone in a camper Facebook group had used this for their roof and had great results. I tried it and was pleased with how it cleaned. The main reason I purchased this brand is because it has a protectant in it also. It didn’t get out some of the dark spots with just a soft brush but did when I used a magic eraser on it. I would buy it again.

I used this on my Jayco 28.5 with good roof cleaning results. The downside was the streaking on the side walls, which I did not expect. The directions caution you, and I thought I was rinsing completely, but not. I had to go back over the sides with my scrubbing brush. It came off with a light rubbing. The only way I see to prevent this is to wash the camper after the treatment each time.How well does it clean and protect? Washing a five-star, protection is an unknown. Order a spray bottle if you do not have one. False misleading advertising.

this was recommended by a friend and it worked really well.
