Iron Out Rust Stain Remover Powder, 1 lb 12 oz, and Powerful Gel Spray, 16 fl oz

Definitely buy over and over

This product is amazing! It worked well on hard water stains in my shower and toilet. I could not find anything else that worked but this was easy to use with no long wait and work very well.

Because I have such harsh well water, even with a water softener system, I use Iron to keep my toilet back and bowl stain free and have for years. I decided to give Iron Out spray a try on my sinks and bath tub/shower. We'll see how that plays out since I've only used it a few times.

Spray on, wait a few seconds and wipe off. Truly that simple.

The powder works amazing the spray is useless

I had terrible stains because we have severe hard water issues in the toilet. I had tried many things but nothing worked well. This did the trick after several applications. It was supposed to be gel but it really wasn't so it will not stay where you spray it. I just saturated toilet tissue and stuck it over the stains. It seems really toxic so I wore eye protection and a charcoal-type mask, not the type mask you wear for Covid but the ones you wear soldering metals. And still, I felt it was quite potent in smell and I could feel it inside my body. It might have worked better if I had a window in this bathroom but I don't. If I use it again I will try to use a fan to circulate the air better. I have not used the powder.

Works great for hard water jobs

I buy this product religiously for my stains. However, the spray bottle does not work and Amazon refuses to return. The spray product was not used due to defective sprayer.
