Great cleaner!
I have a composite marble sink (white), into which I dropped some saracha powder (of all things), where the sink developed a red spot. I've tried everything to get that stubborn spot out, and thought I'd give this one last try, since the product information said it &#34;pulls up&#34; stains and removes them. While the spot is still visible, it is very much less so, and I expect it to disappear after some continued use. I used it full strength directly on the spot, soaking paper towels to keep it in place. After a day, I'd say the spot was half gone, after two days, 75%, and as I keep at it, I expect it will be gone altogether.<br /><br />In addition, I cleaned the entire sink following mfg instructions, and the whole sink came out bright and clean. I've tried it on other areas - porch (concrete) stains, water stains on a glass shower door, and a faux marble sink, and each use proved the value of this product for much more than a stone cleaner.<br /><br />It is harsh, so wear gloves and work in a well ventilated area. I'd rinse very well if kids or pets will be nosing around.
