KOFOT White Ox 64 oz. Rust Remover

Took away mold and mildew on our driveway and backyard pool patio. Great product!

Used in toilets and tub to remove rust-like stains from well water. The stains disappeared with very little scrubbing.

I’ve tried a lot of different products remove rust stains from the side of the house and on my landscaping stones. This is the absolute best that I found so far and it’s fairly simple to use. I can recommend this product.

We read the reviews and thought we would give it a try. Wow, we were amazed! We have hard water that as stained our concrete patio and driveway pad and this completely took it off. It was disappearing right in front of us. Absolutely hands down the best hard water rust remover. Used it on our vinyl siding too, took it off after two applications. Highly recommend!! I wish I would have taken before/after pictures. Be sure to use warm water so the product dissolves. Wear gloves and put on a mask as it does have an odor.

Still working on that. Having hard time on applying

This product is as easy as the instructions say. I'm buying more. My sprinkler run off results in rust stains. Rather than elaborate system to remove the iron from my irrigation system, I'll periodically apply this product.

Ruined my pavers. I had rust from spillage of a plant treatment on the other side of the pavers. I tried this to remove the rust and while it faded the rust out a little, it left the white residue. It also did not remove all the rust stain. There really should be a big warning to use on white cement only. Even then I would not use it as it will leave residue. I emailed the company, who is not the same company who sells it, and they never responded. It’s not for any kind of area where you don’t want left over white stuff.

We applied this solution five times to our driveway and even though it did lift some rust stains, it did not fully remove the stains.
