A:  Way to aggressive. These are more for concrete or hard surfaces. I think it would leave marks. I use the green ones on my tires

A:  I haven't tried using them on tires, but yes I think it would be a good idea to use the brushes on them.

A:  Great question--I never thought of using those brushes on my tires. I'm guessing it would be fine. Three pieces of advice, however. Start off with your drill on slow speed. Use lots of water and detergent to prevent abrasion. And as you always see: try a small, inconspicuous area of one tire first, so see the results. Hope that helps. I'm going to be trying one of the brushes on mine.

A:  I don't recommend using this on a tile and grout floor.

A:  Hi, Keith. Thank you for your interest in the RYOBI Hard Bristle Brush Cleaning Kit. I would recommend using the medium bristle brush.

A:  I would test an area with the med bristle. the most important thing is using the correct cleaning products to get the grout dirt lifted

A:  I used it to clean the dried grout on some bathroom tiles and it worked fine with the help of some cleaning agents.

A:  Yes

A:  Haven't tried that. cleaned folding table and truck rubber floor mats. worked great.

A:  It does, but it all depends on what's staining the grout and what you use to clean it with. You may have to try various compounds to see which one(s) do the job for you.

A:  its a waste of money. the brissles wear out after one use. hard to handle. its more trouble than its worth. sounds nice until you use it. i tried it to clean my tub an tile an wash car, you better off to use your hands manually. it dont flex where you want it to go. you have to hold it in right angle just to make it work. its a pain in the aswswss. if head flexed in any direction an had better quality brissles then i say try it but it dont. the head dont spin fast enough to do anything either. one slow aswasewrss speed. use your hands an you be less tired an get way more done.

A:  Hi, Standaman21. Thank you for your interest in the RYOBI Hard Bristle Brush Cleaning Kit. This product is recommend for concrete, brick, and other tough cleaning applications.

A:  They are scratchy, so I wouldn't use them where they could damage tile or other things.
