Rusty scissors? Scratches on your stainless steel sink? Nasty water spots not coming off? These are kind of a must IMO for anybody who prefers to fix things rather than replace them. I've saved several pairs of scissors and garden tools by sanding the rust off, then re-oiling. I've removed persistent water stains and even shallow scratches from our stainless steel kitchen sink. I've buffed scratches out of our pretty stainless steel kitchen garbage can. These are made with rubber impregnated with abrasives. They will wear down, but it appears the abrasive is fully impregnated through the rubber, and they wear down slow, so one set of these should last you a pretty long time. Each one is labeled and a different grade (level of coarseness). The most aggressive will cut through rust with some elbow grease. The least aggressive will buff (but not polish) stainless steel fairly well.

Worked very well on tool tops. Recently I decided to clean up my hand saws. Some were fairly rusted. The accepted method is to soak the saws in a vinegar water solution to loosen the rust....a messy process at best. Remembering my Sandflex blocks, I decided to give them a try. Total home run! Work went quickly with no fuss or mess. A light spray of penetrating oil & a final rub with the medium block to finish off the saw did the trick.

I got these based off a recommendation from a co-worker who also does woodworking. I have a couple machines that the tables have not been cared for at the peak of attention and these were his #1 recommendation. I have used the coarse one so far and it just ate the surface rust off with no effort at all and was not so coarse that it left unsightly scouring marks. If you have cast iron tables on any type of machine, this is the product you need and want for maintaining them. Seriously.

Walked into my garage a day after a huge rain storm, in which a few days before was about 10degrees F. My cast iron sawstop was literally a dust bucket. From zero rust to total rust-over in a few days! Got out the Sandflex that I had purchased a few weeks prior and let some WD-40 sit for 20 minutes and started scrubbing. While the Fine was working, it took a tad too much elbow grease to get the rust off. Moved to the Medium and it was much better.

I really like these sanding blocks. They are a Samsung sponge all the way through it's not just a surface sponge. I found some tools my husband had stored outside that were terribly rusty and between all the different grits they look like new. They actually made cleaning tools fun. Really.

These sanding blocks are amazing. I constantly fight corrosion on my expensive woodworking machines, living in the southern part of the US. As soon as there is a little bit of rust, I use the fine sanding pad. Rust is gone in no time, perfect shine, no deep scratches. I have used the coarse pad to work on my drill press table that had a little bit more corrosion. Same great result. Highly recommend this product, worth the money.

Awesome product. Better value than other rust erasers I've seen, as you get nearly twice the size for the same or less money. All three blocks are very effective at removing the red rust that eats at metal. They can even work off black rust (often referred to as the patina, as black rust doesn't eat at the metal like red and even helps to protect it from red rust) to some degree for those looking for a more polished finish. The course block made rather quick work of cleaning decades of neglect off a machete. For knives and blades in better condition, medium or fine grit is all that's needed. Sandpaper works too. But when it comes down to it, the price is probably about the same between paper and these rubberized blocks (at least that's the case at the time this was written), where these rubber grit blocks are much easier to work with when cleaning metal, largely because they're easier to hold and don't tear like paper.

I bought the 3-block Sandflex kit (fine, medium and coarse) just to experiment with removing tarnish and light rust from hand planes. I've only used the "fine" grit abrasive block on the small plane pictured, and it worked very quickly and very well without getting the sole of the plane out of flat . I like them and will continue experimenting with them.

Saw a video that recommended this product for cleaning garden tools. I see what makes it unique--it's a solid block of grit. It was incredibly easy to use when removing years of sap from garden tools. Packaging describes numerous other uses. I can see why it's so effective! Truly an amazing little block, and this package has 3 different coarsenesses, which is perfect to determine which is best for your particular job!
