RustAid GSX00101 Goof, 1 Gallon GAL Rust Stain Remover (Thrее Рack)

Works pretty well but needs more than one application on most surfaces

We have well water that has a lot of rust in it. We used this to rmove the rust from our shed. It came off easily.

I watch a video about this product and the person only sprayed product on a plastic white fence and stains disappear all by itself. No scrubbing or wiping, just by spraying product. I tried it just like in the video with no luck. If i scrub or wipe after spraying, it would come off. Bought the product thinking all I needed to do was spray product to work, but not true. Even on the bottle, it says just spray and wait for stain to disappear and then rinse. Not as advertise.
