Iron OUT Spray Gel Rust Stain Remover, Remove and Prevent Rust Stains in Bathrooms, Kitchens, Appliances, Laundry, and Outdoors, 16 Ounce, Pack of 6

The only thing I use on my acrylic shower. Just spray on, let soak, and rinse the rust off. It does have a very strong odor that I would avoid breathing.

We have extremely rusty water , works great in our showers !

Great stuff.

If you have WELL WATER rust stains, and just can't get them out , then your miracle is here. Works in the tub AND the toilet. I tried EVERYTHING but nothing worked. Sprayed this stuff in my tub then rinsed in 30 seconds and I was done! It's like magic. It works so fast, you almost can't even see it working lol. Literally by time I Sprayed it on , it was time to rinse it off ! In the toilet, I just poured the bottle in so I didn't have to drain it dry of water, for about 10 minutes , then just flushed. This is the answer you've been looking for.

Works great. Not the best smell.

This product is great to get those hard water stains out of sinks and toilets, it’s easy to use you just have to spray it on the area you would like to get that tough stain out of.

Great for removing rust bathroom stains. Not for metal fixtures.

We have well water at our cottage and the toilets get stained. This stuff works really well with getting out the iron stains. I highly recommend it.
