Alpha Stain Remover Gel Rust 14 oz (400g)

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 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.

I removed a metal rust common in granite. Almost fully gone in 10 minutes of treatment.

It didn’t work on the granite.

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.

This product was recommended to me by the company I hired to fix a faded area on my granite counter top from a rust-removing product. I had purchased a rust remover at the grocery store and squirted it on a paint lid that had rust around the edges. I didnt think to put it on a plate before applying the product, and when I went to clean it up, the product had bleached out the black coloring in the granite. I hired a restoration company to re-penetrate color back into the counter top, and when the guy heard what I did, he showed me the product they use, the Alpha gel rust remover. He said he has never seen it damage a surface, so I purchased a tube and threw out the product I had used. It works great! I cleaned up my outdoor patio furniture using the gel. As soon as it comes in contact with rust, the gel turns purple (cool chemical reaction). I used it without gloves with no issues. It does have an odor, but once the area is adequately rinsed, it is gone. I imagine this tube will last me years. Glad to have the peace of mind of a product that will not damage other surfaces when used!

Pretty good but seems to leave a purplish stain.

Wish I wouldve taken a before n after pic, but as you can imagine, the floor was 10x worse than the walls This stuff took 3 years of rusty water stains and pulled them out of the marble like it was nothing! Not gonna lie, it smells like sulfur/eggs for a few hours but this stuff works miracles.
