Rust Remover for Concrete (60 lb. Drum makes 45 gallons)

I’m seriously impressed with Singerman Laboratories Rust Remover for Concrete! I had some stubborn rust stains that I honestly thought would never come out, but this product proved me wrong. It worked quickly and effectively with very little effort on my part. What I love most is that it didn’t damage or discolor the surrounding concrete—it just lifted the rust right out and left everything looking clean and refreshed. You can actually see the results almost immediately, which is super satisfying. If you’re dealing with tough rust stains on concrete, you may have to apply it more than once, but it works. I highly recommend this product. It does exactly what it promises!

We used this on large rust stains on exposed aggregate concrete, and I’m honestly impressed. Exposed aggregate is usually very hard to clean, but this worked wonders. We followed the directions, kept the area wet, let it sit, and lightly scrubbed before rinsing. The rust stains faded dramatically and some were completely gone. It didn’t damage the concrete or aggregate, and it was much easier than pressure washing or scrubbing endlessly with no results. A little goes a long way once mixed, too. If you’re dealing with rust stains on concrete, especially exposed aggregate, this is absolutely worth trying.

I do write reviews. After using this on rust spots all over my paver brick walkway - and they are 100% gone with zero scrubbing! Amazing stuff. Fair price and works as they say it does. So happy.

The product worked really well on a small stucco retaining wall. Had to do a 2nd application, but it took out 95 percent of the rust. Goes on easy. Then tried it on my concrete birdbath twice and it diminished the rust quite a bit, but did not take away all of the rust. I'm going to do one more application. I think the bird bath base was mixed with something else, preventing the product from working. I'm going to try it on some other items around my house. I would recommend this product.

This stuff is pricey but so is the loss in value of your house when you have iron stains from fertilizer making your driveway and walks look nasty. It makes a full gallon which you must apply within four hours. I suggest using HOT water and getting a small roller brush to apply for larger areas.

This product did a creditable job removing most of the rust stain on my NEW driveway resulting from old rusting roofing nails left by the contractor and left in the gutters after a fairly recent roof job. Of course, making sure the gutters were clean of debris and nails beforehand should be on the prep work list. Also, would highly recommend using a paint mixer tool powered by a drill in the preparation of the fluid instead of a paint stick because of the quick efficiency, better mixing and absence of clumps of powder medium. Would also recommend using a concrete trowel or something similar to spread and evenly distribute the thick fluid for better results. I waited an hour before washing it off with a power nozzle according to instructions and ensured enough water to protect the grass from the chemical runoff at the edge of the driveway.

This product definitely works!

Love this product. We got rust orange rust spots on our new Unilock patio after my husband put lime down next to it & it got on the patio. I bought this on Amazon & it worked great. Most of it came off with one application & all of it came off with just 2 applications. I let it set for about 15 minutes both times. I tried everything before this with no luck. Excellent product. The price is so worth it. I made small batches & cleaned small areas so it didn’t dry up. I used a pop up tent to keep it out of the sun so it didn’t dry up. I painted it on with a paint brush. So Happy I found this product I wanted to spread the word. Love,💕 it. It also washes up with just water. The container & the brush cleaned easily with just water. Wear gloves.

We had rust stains on the concrete from garden pots and we tried several chemical and non chemical solutions and high pressure hosing to remove the stains. Nothing worked. This product removed all stains first try. It's just magic. Finally a product that does what it claims to do. Thank you!!

I had rust spots on my concrete fro lawn fertilizer. This product was excellent and i highly recommend it for rust removal. Followed the directions and with very little effort I had all stains completely ( not slightly), removed in 30 min You can't tell where any stains were and the product did not discolor the concrete. Very happy

Very expensive but very effective. I made a real mess of some new slabs with lawn fertilizer and thought I was done for. Found this product after a bit of research on YouTube. I made a small batch with 43g of the powder and 250ml water to make a gel. Applied with a brush and let stand for 20 mins. Hosed off the residue and gave a light brush. Rust staining came right off so I made several more small batches to apply and remove. Really great results, I now have only a few stains left where I haven't applied it properly.

Sort of does what it's supposed to do not look for excellent results if the stain has been there for over 6 months anything with a stain right away I think it would work awesome it does clean up your concrete so if you can mix it into a spray bottle and leave it there and agitate it you can do your whole driveway it look brand new. Does take some of the standing way but doesn't do deep penetration do a test area before and follow instructions it'll work but like I said only works on new fresh stains and it does brighten the concrete quite a bit as expected because you are cleaning

It worked as described. It even took old paint splats off the driveway...... Just brush on lightly and wait 20 minutes then rinse off. Best done on a hot day before a rainshower, seems to work even better..
