Removed All My Stains

Elevated all my iron stains on my concrete driveway.

Best mineral remover
Size: 128 Fl Oz (Pack of 4) Style: Liquid Rust Stain Remover
We have tough mineral staining on the concrete sidewalks and curbs. One coat of this and the concrete is 80% clearer. It does not get back to new, but so much better. Best product I have tried, and I have tried many!

A lot depends on the situation
Size: 128 Fl Oz (Pack of 1) Style: Liquid Rust Stain Remover
I was looking for a way to remove rust stains from the frame of my aluminum stom door - left by steel screws that rusted in place and stained the powdercoat. I got aluminum replacement screws, and hoped to use the RidORust to remove the stains before re-installing. The product did not work on the rust stains in my door frame. I poured a little RidORust into a bowl and applied generously using a soaked cloth, and made 4 applications. It may have lightened a bit, but the stains are still there. So I tossed the rusty screws into the solution. The next day, the rusty screws looked LIKE NEW. I may not have had enough patience on the door frame applications, but then I don't have scads of time, either. It may also be that I couldn't keep the vertical outdoor surface wet with it for long enough, or that the powdercoat would never have yielded to the solution. I'd love to hear of any ideas to keep the product from drying on vertical surface longer so it has time to work. Still, I can see that the product does work and I'll have many other applications for it! ... show more
