Whink Rust Oxy 22 Ounce

Product does not work even when poured directly on wet concrete, scrubbed & allowed to sit for an hour. I have been using liquid whink rust remover to remove ground water stains from our walkway and siding. It works great and literally within seconds. I needed a larger quantity than I've been able to get at Walmart and was thrilled to find a product I could put in my chemical sprayer. I followed the directions- one cup dissolved in one gallon of warm water, apply, scrub, allow to sit (5-10 minutes), rinse. There was no improvement in the stain. So I poured powder directly on the concrete, scrubbed & let sit with only slight improvement.

The only thing that removes rust stains from the inside of the toilet bowl! I use it on a wet scrubby like a scouring powder or sprinkle it straight from the container. You can only do this if you have WHITE china fixtures! If you have stubborn stains, don't dilute it. Use it as is like a scouring powder. Have tried all the other products that claim to remove rust. This is the only thing that works!

Our town has hard water and I could scrub and scrub and never get the stains to go away in the toilet. I was embarrassed for guest to see it as it looked dirty. But this stuff did the job!!! So easy to use, just pour it in and let is sit for a bit. I scrubbed too and now the toilets look brand new!!! Already bought some more :)

Good product for cleaning... but to expensive.

took that rust out of my clothes! we have very rusty water and after a couple of washes my whites are brighter and brighter each time!

I used this to remove rust stains in the toilet. The water has a high iron content. This product was incredible for that. I literally just squirted it on the rust staining, with no scrubbing at all as I had done trying other products. Literally within like 20 seconds, the stains were completely gone. On the bottle it does say only use on white colored toilets. Highly recommend. Best product I have found.
