Rated 5.0 out of 5.0 by Great product We have a lot o rust and this product removes it great along with the iron August 11, 2015
Rated 5.0 out of 5.0 by worked as it said it would Removed years of well water stains from my walkway, walls, windows and stone without much effort, and hosen off fine. July 7, 2015
Rated 4.0 out of 5.0 by Rusty - Mixed Results Tried this on three difference types of stains, walkway, wall and in the bath. We had to use multi applications on the walkway and still had a very fate discoloring left, but otherwise it worked well with little effort. The wall worked to best, just one spray and a light rub, we had a clean wall. Last was the bath and with the build-up water spots, age old drippy faucets we had some stains that cleaned up well. Overall, it did everything it said, as not all stain can be completely removed as stated "removes most rust spots and stains". Now we just have to get rid of those water spot build-up. May 8, 2015
Rated 3.0 out of 5.0 by Mixed Results A lot of elbow-grease is needed in order to get the best results on most projects. However, if the rust hasn't started to build-up it will handily spray it away. We tried this on some rust marks on the garage floor and it did lighten them after much hard scrubbing with a scrub brush, but, not a substantial amount of improvement. I was able to spray and wipe away rust from a metal shower holder - but only some of the spots would easily wipe away. May 28, 2015
Rated 4.0 out of 5.0 by Works on multiple surfaces I got this product to try to remove rust stains from fabric on patio furniture. If you follow the instructions, it works better than any other product or method I have tried and did, in fact, help to lighten and remove rust stains from my medium green upholstered cushions. On a lark, I tried it on a white shirt with rust stains and it worked there, too, but with some effort. Follow the instructions! Pre-test a spot before spraying it everywhere. Wear older clothing and watch it help remove stains. April 28, 2015
Rated 5.0 out of 5.0 by Best Purchase Ever This product worked very well to help me clean years of iron off my brick around a faucet. Sprayed it on, scrubbed it a little, washed it off, done. Had to do a couple small spots a second time, very easy to use and effective. May 12, 2015
Rated 4.0 out of 5.0 by Pretty Powerful Stuff This spray worked great to clear away surface rust on a grill. I used it along with a sanding block (lightly) and it cleared the surface rust up very quickly and easily May 12, 2015
Rated 1.0 out of 5.0 by Too good to be true... Don't know why searching Home Depot website with the tag 'phosphoric acid' returns this product, since the label clearly states that it's a mix of OXALIC and CITRIC acids. Must be considered a "substitute". I'm glad it's "enviro-safe", but it's worth virtually nothing as a rust remover on a vehicle chassis, nor on an electrical enclosure. A squirt and a rag used per instructions yields no satisfactory results. Had to break out the drill and wire wheel and go the labor-intensive route anyway. Next time I'll just get straight phosphoric acid. PS: I live in a very HUMID locale (S. FL)... does this work better in arid environments? October 7, 2012
