I was sceptical about the purchase as few users have mentioned as useless product. Those who mention it as useless does not mention for what purpose they use and how they used. I made a 2 percent concentrate using 10 gm powder in 500ml water. Used it on one tile in bathroom to remove water marks. It worked very well. Attaching the photos as well. I used gloves and mask as a precaution.

Worst product ,waste of money

Good results after used. But acid reaction shown on user ft not used sefty.

Not sure about quality or strength. Doesn't seem to be quite as strong as I expected it to be.

Worked for stainless steel stains

Real fabrics brightner

Not effective for removing rust ( corroded part from hardware, accessories)

This item is useless don't buy it. It doesn't remove any strains
