Singerman Laboratories Rust Remover for Concrete (22 oz makes one gallon)

I work in Palm Springs California as a handyman for 22 HOA and over 8000 personal clients. Because of all of the pools in the area. I am constantly asked to do rust removal out of concrete. I have used many products.Most the time I am crossing my fingers with a wire brush, physically pulling the rust stain out of the concrete. Today I followed the directions on mixing the material. Applied the solution to many rusted concrete locations. And when I came around to begin the physical, scrubbing portion of the work. The rust was already disappearing! I whole heartedly back this product. I am very happy with the results.

This rust remover worked very well, and I am most pleased. It worked on the lighter rust stains on my concrete patio with just one application, while deeper stains required a few applications. I first tested the product on an inconspicuous place to make sure it would not harm the surrounding, non-stained concrete. When I determined that it safely worked on the concrete, I used it on the entire stained area. I recommend Singerman Laboratories Rust Remover.

I have tried many different products to get off battery rust stains off new concrete. This product took it right off. Stain disappeared right before my eyes. Took only minutes for the stain to disappear. Was very skeptical as nothing else had worked. Would very much recommend this product!!

It removed the large rust stains on my porch from a metal bench. I wish it wasn’t so expensive but it worked great. It left a little discoloration in the cement but not too noticeable.

We had a really tough rust stain on the driveway that a plumber left after doing some work. I tried EVERYTHING. After days of scrubbing it with baking soda & vinegar, lemon juice, driveway / outdoor stain cleaning products, and the pressure washer it was still pretty visible, just maybe very slightly faded. A neighbor recommended this stuff and I'm so glad he did! It's the only thing I've found that can effectively lift rust from the driveway. It smells pretty bad as the other reviews mentioned, but it does it's job. Make sure you store it tightly, seems to lose it's power if it sits for a long time. Super easy to use though, highly reccommend this product
