Iron OUT Outdoor Rust Stain Remover

Well I had no expectations when I went to use this product. I really didn't expect it to work. To my surprise, Iron OUT Liquid Rust Stain Remover really did a great job. I installed a shallow well water pump to water my grass and after a year and a half, I had some pretty good well water stains on the house. I wish I would have taken some before and after photos to show how well this product works. I usually don't do reviews, but I feel that others that have a well water system to water their grass can also benefit from this product. It took a couple of applications in the stubborn areas but took the rust stains off the house and stains off various objects around the house. I was so happy that I purchased more for future applications.

Had lots of rust on my curbs after record rainfall (they say it comes from rebar in the sidewalks) Applied this product with garden sprayer, per instructions. Within minutes the rust was gone. However, it left the concrete where the rust spots were much whiter than the the rest of the curb. Re-applied the product with sprayer then used a fluffy 4 inch paint roller with pole attachment to spread it over all concrete surfaces. A little goes a long way. Absolutely great results. Needed 2 gallons, but well worth it

Absolutely great! Heavy rusty water marks on white fence other products didn't remove any. This one removed 95% with first application and the rest with the second one.

My sprinkler system has rust and leaves my driveway stained. This rust remover works fairly well. It removes most of the staining. However, some spots require you to use a second coat of spray. The product is easy to use.

Works incredibly well. We have well water and do get rust stains. Removes without scrubbing. This is a repeat purchase.

It made my brown stained sidewalk, curb, and driveway look new again. Like it was bleached almost. I sprayed it on and power washed but I’m not sure it needed it although my stains were pretty bad. I would certainly recommend it and buy it again. I think if I use it every year or so, I won’t need to power wash. It’s almost too good because the neighbors must be really jealous.

It works! It removed the stains on my driveway. I tried spraying first but apparently I needed thicker layers, so I just poured it directly from the container. If the stain persist just apply more. It's effective, easy to apply, but wear gloves and a mask. The spray version works too for small areas.

Didn't work for what I bought it for. I got it to take the rust off quartz crystals and it didn't work well at all

This worked amazingly to remove a rust stain from white brick. I simply sprayed it on and the rust disappeared. No scrubbing required.

I mistakenly sprayed moss killer on my granite walls which left some ugly yellow stains. I tried all sorts of things to remove unsuccessfully. This product, albeit expensive, worked well.

Très bon produit

Took very little stain off and left a white residue

Did not do a very good job and also stained the driveway.
