Size:1.37 Pound (Pack of 1) Singerman Laboratories Rust Stain Remover for Concrete is the most effective cleaner in the marketplace for removing rust stains from concrete and natural stone. Makes the concrete or stone surface look like new. Frankly, we've been unable to find another product that actually removes rust stains from concrete, except those that are so harsh that they remove the stain by also removing the concrete. It is supplied as a white powder which is mixed with water just before application, forming a clear gel. The rust stain remover is spread on the surface and left for one to fifteen minutes, depending on the severity of the stain; the stain disappears without scrubbing. Rinse thoroughly to prevent redeposition of the stain. Will not harm grass or other vegetation.

Removes well water stains
This product is legit. I tried everything to get the iron stains off my granite light post caused by years of unfiltered sprinkler water. I bought the strongest pressure washer and it didn’t even make a difference. A neighbor had me researching muriatic acid when I came across a YouTube of this product. I didn’t really want to use acid being that we are in well water. I gave this product a try expecting to be disappointed, but wow.I saw immediate results with each application. My staining was very dark and many years old so it took four applications to remove it completely. I also left the applications on for about 30-40 minutes vs the 15 in the instructions. Look at my light post. Looks brand new. Neighbors are all in shock. Best part is this product is non-toxic. It’s been two weeks and my grass did not have any negative impact from the product.

Solid Product. No hype.
Saw a review of the product on YouTube and read the company advertising about it. I was impressed because it isn’t easy to get rust or battery acid stains off a driveway. I had a local company give a quote. They wanted $500 and said they’d have to do the whole driveway even though I only had two small, but ugly, problem areas. I kept looking for a product I could apply myself and found this. Super easy to apply and acts very fast. Repeated applications help. The area is still somewhat visible but I’d say it’s 90% or higher better than it was and I can still do more applications if I want. I’m very satisfied and definitely recommend it.

Removes rust within seconds.
Every time my dad comes to my house, his truck leaks rust onto my driveway. This rust has been on my drive way for years, and I have tried bleach, baking soda, a Power Washer, and other things to remove this rust and it never would work. After putting the mixture on my driveway, I saw instant results in a matter of seconds. The second picture shows after the second application. This is a miracle worker. I am so glad I discovered this product on Amazon. I would have given this product 5 stars but some traces of rust is still a little visible, but I am amazed with the results. I’m sure if I keep applying the remaining traces of rust will completely disappear.

Works When Other Products Wont
A few years ago our landscaper got some fertilizer pellets on our pavers. I tried everything I could think of to remove these quarter and fifty cent piece brown spots, nothing worked. Over the years they have lightened in color, but are still there. Fast forward five years and here's me applying fertilizer and being extremely careful not to broadcast them on my driveway. What I didn't count on was a heavy rainfall (deluge) which caused the round granules to float out of the flower beds. I discovered this product and both old and new brown spots are gone. YES!!!

The stuff rocks!
I had chemical overspray on the sidewalk from the fertilizer treatment on bushes. I tried four different chemicals two of them acids, nothing worked. This product made it disappear in front of my eyes,very cool! It is much less toxic than acid‘s, which have to be neutralized and kill the grass and bushes. It does not etch the concrete and you can use at half strength to work your way into stance. The stuff is really expensive but it works.

It works!
I've done some stupid things, most recently putting down a heavy iron fertilizer and not thinking to make sure I didn't get any on my concrete... it was TERRIBLE, rust acne all over my <2 year old driveway... I found this product and knew it wasn't going to be a fun cleanup process but a process I needed to do. Biggest pointer I can give is to make sure the gel sits on the rust, rubbing it in so there is no longer a gel was ineffective. In the end it took out most of my stains... still some but its WAY Better than before.

One Container Only Covered 3 Sidewalk Squares, Puts A White Film Over Stain
I purchased this product to clean hard water rust stains off my sidewalk that were caused by my sprinkler system. I followed the directions to a tee, which required some patients since it takes a good while to properly mix this with one gallon of water. That being side, I did mix it by hand using a stir stick. I was able to mix it up into a thick gel, which was how it was described by the manufacturer.Once I got the proper mix consistency I began spreading it on one sidewalk square with a new small stiff bristle brush. I let it sit for 20 minutes and rinsed it off with my power washer. It certainly lightened the hard water rust stains, but did not completely remove them. It seemed to put a white film on top of the stains. In fact, you can see the brush marks from the bristle brush.Another issue though is the price to product. You can not stretch out this product since it becomes a thick gel. I was only able to clean 3 sidewalk squares before my bucket was bone dry of the product. At this price, I would expect to be able to do more.I am not sure what I will do to finish my project. Try another product or purchase several more containers of this, but that will become pricey. I will update my review if I try a different product and compare the results.

Does not remove rust stains
I mixed and applied the rust remover according to the instructions. Tried it on different concrete surfaces including colored concrete where Scotts fertilizer with iron left a number of rust spots and stains. Singerman's product did not remove the rust stains. It did hide some stains with a white film that didn't wash off. I ended up using a wire brush that helped reduce the size of some of the stains.
