Rusterizer Rust Remover, 32oz - Remove Rust, Calcium, & Lime With No Scrubbing Or Wiping.

I was hoping this product would be the end of scrubbing off rust with harsh chemicals. It did remove 75% of rust lines from the concrete garage floor. The rust was from a snowplow that left 8-10 lines 2 inch wide X 5 ft. I had to use the entire bottle. A lot of the Rusterizer was wasted when it ran down the concrete. It needed to sit a few hours then rinsed off. The next day after drying,most of the rust appeared faded.It was expensive IMO and worked good but not great. Make sure you wear gloves as it is irritating to skin.

This product worked better than all the others I have tried. I used it to remove the surface rust on old table saws and drill presses. I would have given it 5 stars if it wasn’t for the spray nozzle that failed after the first day. I have tried many commercial chemical spray nozzles and they all have failed even worse. The chemicals in this solution must eat the rubber seals in the spray nozzles causing them to fail sometimes right away. A suggestion for anyone buying this product is to try running some water through the spray nozzle after each use, and not to store it with the spray nozzle attached to the bottle....

I had accidentally gotten quite a bit of fertilizer on the cool deck around my pool. The Rusterizer removed some of it, but not all. Rusterizer DOES work extremely well on plain concrete or vinyl siding though.I intend to let the remaining spots have time to fade over the fall and winter and will reapply additional Rusterizer in the spring if needed. All in all, this is a good product . . . just does not completely get everything off cool deck.

I replaced the sprayer after I thought it got clogged but the second one quit working after using one time. I don't think this worksgreat going thru a sprayer. Also, it leaves a white film on old aluminum which makes those pans I tried to clean useless. Great on beaters for my mixer and old coins, though you need to rub a bit to get a shine.

I have rust stains on my white lamp posts and pavers due to the sprinkler system feeding directly from my well. I have purhcased various products and spent endless hours scrubbing and cleaning to remove the rust but nothing seemed to work.Few days ago I received an email from Amazon regarding this product and was quite hesitant at first but of course had nothing to lose so I decided to just buy this product as well and give it a try.I happened to be outside when the UPS truck arrived. I opened the box, attached the spray nozzle and walked over to my now yellow/rust stained lamp posts and gave it 2 pumps. Thinking nothing would happen I was shcoked and amazed. The stains disappeared in millisenconds. I am one happy customer and buying every ounce available.

Don't believe ALL hype, only some. I had rust stains on the driveway from iron fertilizer, it took off the lighter stains using A LOT of this product, elbow grease and a steel brush. It lightened the darker ones but did not remove them. It also eats the spray bottle at the pump as it must eat the plastic down. Do they make all metal spray bottles? Probably a good use for small rust areas... I had a bout a third of a one car driveway to un-rust.

Received today and could not wait to try it. I had a large rust spot running down the side of my stucco home. I knew what caused it an air conditioner that needed to be flushed out. It'd several people look at it and ride all kinds of of methods toget rid of it . In fact I tried bleach and water nod hd someon ty pressure wash it. It was still there until today. It is now gone gone . I sprayed Rusterizer on it and couldn't believe my eyes it just disappeared. I then hosed the area. Thank you for a great product.

It took the rust right off of my driveway with no sweat. I rinsed it very well afterwards with water for about 4 minutes. 3 days later I noticed the grass was dying. It's 4 days later and the grass where I sprayed is fried. It is dead. I would recommend neutralizing it with Baking Soda after you use it then rinse it away in order to lessen the odds of your grass or plants being killed.
