Questions & Answers
Here is a message from my son - His bathroom floor was covered in dried grout, so he went to his father-in-law for assistance. It was coated with a baking soda paste, and he stated that it did the job without scratching the tile. I have not seen it yet, but I do not doubt it.
If I were to use this on fabric, I wouldn't. There is a risk of fabric abrade and tears. For cleaning fabric, if there is anything on it that needs to be cleaned, use a very soft brush with a mild detergent.
Wire brushes are similar to this, but they are nylon instead. With such a gadget you might be able to clean a fuel tank, but I'm not sure. In order for it to work, it must be attached to a drill, and then it can reach only so far. There is no need to weld on an extension (unless you weld one on)
The only wood I have ever used was plastic. Try as I might, removing dried grout was useless. If you have not tried it, I recommend you do so. Wood might work well with it. This would be better than steel wool for speeding up the process.

Ted here, the Disco brush is a superb little brush you can use with an electric drill to clean all kinds of things. Last but not least you can use it with a rim brush to clean your car rims it works nicely with soap and water.

I saw that first. I was initially hesitant about the product because I thought it might be too rough and too flimsy. There is a room where I paint in which I have tile floors and rock walls. Despite both the rocks and cement walls being painted, the paint came off with ease! I was a little worried it would scratch my tile floors, but I added some soap and a little hair conditioner and it stopped scratching. To be fair, it should have been used on the walls first, then the floor, so it would be less harsh, but it was still It was easy to accomplish the results I wanted and my room is much more organized at the end.

As a second step, mix baking soda with a bit of vinegar and water to form a loose paste. As a third step, dip the tile and touch it with a drill. Those tiles and grout are the cleanest I've ever seen. Make your skin sparkle by rinsing and sprinkling. Grout was not worn away and no scratches were found on the tile. Mold has not returned to spray-on tiles after sealant was applied. This is the first time it's stayed clear for this long, and the only difference in my previous attempts was I did not have this scrubber. I think it could save many lives and limbs!.

The grout removal solution we bought worked great to take dried grout off tiles. No one had them, no matter where we looked. With zero problems, they held up well to the heavy work.

I liked this a lot. It really sped up things for me when I used it along with some CLR on my rusty barbell. Although it wasn't quite as effective on the knurling due to the fibers being quite thick and not reaching those tiny crevices, I had a brass wire brush for that, so all was well.

I am very happy with how it worked out!.

Applied to tubs & tiles as well. We have tried many, many cleaners and scrubbers, but none of them worked. This worked great for "scouring" the old vinyl tub we have. The idea to try it was born out of this. I TRULY DO WORK! And I am glad I didn't get the one with coarser (harder) bristles. We were pleased with the results, and the tub was not scratched at all. This method worked on the tiles as well. As opposed to what we thought would be the case. It is not necessary to replace the old tub because we are keeping it now and our future bathroom renovation will be cheaper! The best of the Best )
Highly Recommended.

The scrub pad was used to scrub off mortar and grout that had set on top of the tile floor when I reglazed it After my shower, I dried off. I used vinegar to remove the grout, and the process took some time, but it was not damaging to the tile or scratching the surface. It appears that the cup brush can be used for a variety of things, and it appears to hold up well.
