Reliable 1 Super Spray All Purpose Cleaner (2, 32oz) (2)

I have spent a lot of money over many years on products that claim to remove black streaks from RVs. This is the first product that has actually done what it claimed. I definitely recommend this product and will be buying it again. It was so easy, spray on, wipe off.

If there was an option to give more stars, I would! This removed the black streaks on the fiberglass cap of my RV after a winter or storage in the NE. Some mention that you still need to wipe with some elbow grease, but for me, this product took the streaks off EFFORTLESSLY! Outstanding find. Thanks for a product that really does what is says.

The product does what it says will do with little effort.

I purchased this product after seeing a YouTube video from an RV dealer who renovates older models. Came highly recommend to remove those annoying streaks that develop from roof sealant exposed to the elements. MIND BLOWN! Product works as described! RV looks like the day she was freshly painted. Product was shipped timely and well packaged.

Awaiting warmer weather to use

Just tried product -- haven't formed an opinion as yet

My heart was not working well for the last couple of years. SOOOO my RV 5th wheel toy-hauler went begging for care. I live in Oregon and the RV is on the street, under trees, in rain, leaves, and other black streaks causers. Now that my heart has been overhauled I decided to wash the rig. The black streaks and spots on the slanted front defied the brush, scrubbers, and sponges, regardless of the cleaning agents I had. In desperation I ordered this product not expecting much. WOW was I delighted to see the black melt away.Granted there is still a lot of elbow grease required, BUT I can now see there is light at the end of the tunnel. I was so desperate I had dug out the 3000 grit sand paper. I didn't want to thin out the already thin fiberglass but I was sure there was no alternative, till I received this product.Don't wait, order this one.

I tried several highly rated products from Amazon, but this is the ONLY one that worked! A terry cloth and this spray, removed black streaks from aluminum on my white painted aluminum horse trailer. Minimal amount of elbow grease required. Highly recommend for getting rid of black streak/staining on my horse trailer!!
