Alpha Stain Remover Gel Rust 14 oz (400g)

This does not work well on deep rust stains. I’ve tried at least 2 dozen applications and stains are still present. I’m sure it’s good for surface rust but does very little for deep stains

This product is almost magic on rust stains on porous stone. We have a limestone outdoor patio floor. A metal table had begun to rust and we didnt notice soon enough. There were four round significant rust stains. We had tried many things and came upon this product. It is easy to use, works almost instantly, and you know it is working because the rust turns purple. Some of the stains required multiple applications but eventually, there were unnoticeable. We found that applying a bit of the gel and using a wooden popsicle stick to move it around really helped to draw out the rust. Be sure to flush with lots of water and decent pressure from your hose to be sure the purple color is fully removed.

used on several different types of rust stains, works within minutes versus trying to put a poultice and let sit for a day or two...would recommend

I followed a You Tube video on how to remove rust from our outside Travertine pavers with this Alpha Stain Remover Gel. It worked perfectly, removing all the rust spots!

This is very quick and effective. I used it on stonewall in my bathroom. It worked great.

Wow!! We used this due to the iron in our well water causing rust stains. The difference it made was amazing BUT the smell is unbearable for longer than 5 mins and the smell lingers after your done for a day or so. We did it one section of the shower at a time

Had a large rust stain on my granite door step resulting from a metal sculpture placed there for several years. Did two applications and the rust is gone. I thought the product was pricey, but the tube is a lot larger than I expected and it worked! Saved me from having to buy a new, expensive piece of granite.

This product doesnt work and its non-refundable. I am very upset that I wasted so much money.

The tile and a half on the left are after using the stain remover. The right tiles are what they looked like before. This stuff is a life saver. The travertine shower tiles were all severely stained from hard well water. No scrubbing required, just left the thin layer of gel on for a few minutes, wiped away, and rinsed and the tiles have no orange left on them.

It didn’t work on the granite.
