STAR BRITERust Stain Remover - 22 OZ (089222P)

This is THE best product ever!! Spray on rust stain, walk away. Spray again later. Walk away...... keep doing it until it's absolutely GONE! Without scrubbing! It's amazing. Just don't get on your skin. I didn't burn, but it did feel funny. Would definitely recommend (while using gloves)!

I was wondering how good this would work. It was amazing!! Fast and easy to use on a bad rust stain. Definitely a wothwhile product.

The bottle comes with a spray option, but I don't recommend using it, as it's more of a mist than a spray. When I used the mist, I got an immediate burning in my throat, even though I was outside and upwind. Best to just put some on a rag, and even then, you'll need a good N95 mask at a minimum.That said, you can see that it was remarkably effective on a several year old stain, where my rusty old gutters leaked onto my painted lower roof. If my rust had not bee mixed in with some hard water deposits, I suspect this product would have removed all the rust stains.

Most stuff i have tried on rust and did not work. This stuff works great and removed most of the rust 90-95%. I would buy again and would recommend.

I left a metal grill pan on my vinyl countertop for too long. Tried everything to get the rust off. This worked great. It took a couple of applications, about 30 minutes to let it sit and then elbow grease with a stainless steel scrubber. Super happy. 👌

This spray is practically miraculous. I’ve had hard water iron stains on one side of my car from our lawn sprinklers for a couple years and have tried many things that requires elbow grease to use and nothing worked. I was about to resort to expensive detailing but then found this product in my research. I literally sprayed it on, waited a few minutes, rinsed, then sprayed, waited and lightly wiped then rinsed and the stains AND black scuff marks I’ve accumulated are GONE. So easy! And while I waited for it to work on my car I quick sprayed my nearby PVC fence that was also sprinkler stained and didn’t have to wipe at all. One spray and rinse for most fence stains then another round of spray and rinse to remove any remaining rust stains. No wiping! It even worked on my drain pipe and vinyl siding trim and the stucco on the foundation. I’d buy this again in bulk!

I bought this because of all the 5 star reviews, but it is completely useless we applied it 8 times to some rusted bolts and it had no effect, even though we waited a while between applications and THEY DO NOT ALLOW RETURNS! a complete waste of time and money

We purchased this product to get rid of some rust spots that we had on the deck of our boat from taking a grill out on it. We followed the directions on the bottle of spraying it and scrubbing it in and then let it sit for 1-2 minutes, we personally did 5 minutes and then rinsed it off with the hose. Let me just say the spots came off like a piece of dirt. It was amazing! We then went around the entire boat and did all the rust spots from any screws that had previously rusted and left some stains and again, they came right out! HIGHLY recommend this product if your looking to get rust spots off of your boat!
