Black Streak Remover, Stain Remover for Boats and RVs, 32 Fl Oz Spray Bottle

does not come with a sprayer as shown in the picture

This product works great for black streaks on RV's. Had stubborn black streaks on my RV that other well known RV black streak removers cleaners would not completely remove. Sprayed on the UN DUZ let sit for 30 seconds and wiped right off easily . All black streaks were gone . worked on both fiberglass and on glass windows that had stubborn streaks. after spraying and wiping off area, simply rinse off with water to remove any residue and all good

This product didn’t come close to removing the black streaks from my RV.

I used 2 other black streak removers on my camper before trying this one. Not even kidding, worked like an eraser. Wiped right off. Will certainly get a few more bottles to maintain the rig.

It promises a lot, but ourMotor home looked no different after a lot of elbow grease. Just hype and false promise

This product did NOTHING to remove black streaks on fiberglass. I had to turn to diluted bleach in water to remove streaks. What did work was scuff erasers with a little soapy cleaner.Don't waste your time or money.

I tried the product several times on my RV's dark stains.Zero affect. Useless. They should block this product from sale, imo.

YouTube’s Capt’n Q recommends Un Duz It and that’s good enough for me
