American Hydro Systems 2662 Rid O Liquid Rust Stain Remover, 1-Gallon Bottle, 128 Fl Oz (Pack of 1)

The best product you will ever buy. We used it to clean a shower and toilet with well water rust stains. Wish we knew about it 20 years ago.

This stuff is amazing!

Wish I could give 100 ⭐'s! I have always hated our sidewalk with the discoloration from our sprinkler system. My husband said there is nothing we can do about it.. I decided to try this product and although my husband was very apprehensive, he sprayed it on and voila! Very impressed!!

Rid Rust is a great product it does what it says. I used this product on my driveway with a spray bottle where rust was from the iron in my sprinkler system. Rid Rust removed all of it just like new.

First use on exterior stone (real) lamp post and opaque light fixture. Sprayed on, let it soak for a short time, then used an electric power washer. Came extremely clean.... IMPRESSED.Next project... small stones around perimeter of house. Tried to power wash, but was too messy, so I gave up. Came out the next morning and thought the stones were much cleaner (iron in irrigation). My wife also commented without me prompting. I just put down another spray and just walked away. I am always skeptical, but this really did work.

Used on garage floor twice did not make a dent. I’d like to return it, but I guess I can’t stop this terrible

My home is on a well and my fiberglass shower had sections almost as yellow/gold as the 5 stars I have given this product. If I went for over two weeks without hand cleaning, it took two hours to (mostly) get rid of the rust looking residue.I received Rid O'Rust on a day when it was at its worse. I sprayed the shower, waited 20 minutes and 70% was gone. I rinsed and applied more to the sections that had not been cleared off. 20 minutes later, they were gone also. No scrubbing or other action was necessary - just a rinse with the hand held shower head. What I noticed was that the area not cleared on the first application was not cleared at all. This product does not seem to reduce the areas of stain - it's either cleared or not cleared. However, as stated, a second application removed all.What I didn't realize that the rust had accumulated on areas of the shower that I didn't, at first, see. I was only after I cleared away the majority of the stain that I was able to see the additional rust. It only took another application to bring the entire shower to snowy white.I read the reviews before purchasing - I always read the 1-star​ reviews first - I have no idea of why the product didn't work for them. All I know is that the fiberglass shower that I used this product on is as white as when it was new.

I completed 3 applications on the corner of the top of my concrete front steps. It was a small but pretty rusty area on corner of step from cast iron gates. It’s easy to pour on & rinse off. However directions were a bit skimpy. After the 3 applications I noticed tiny flecks of white around the rust stain. So, it works but I fear I will have to repeat this procedure many times before I see an improvement in appearance. I’ll increase the rating from a 3 if it actually makes a visually significant difference after I finish the whole container if I have to. Even though it didn’t make a satisfactory change yet I’m giving it a 3 because I did notice some specks where it got lighter & nothing else has worked.
