Unitedlys® Oxalic Acid Powder 380 Grams | All-Purpose Tiles, Granite, Stains, Rust & Floor Cleaner | Professional Strength Stain Remover, Rust Remover & Tile Cleaner

Good result than expected. Good quality

Worst product......no result. It showed as if something needs to packed just for the sake of selling oxalic acid. No result. Wastage of money.

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

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.

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

This product worked wonders on the rust stains in my bathroom. I mixed the oxalic acid powder with water and applied it to the affected areas, and the rust disappeared like magic. It’s powerful, so make sure to use gloves and follow the safety instructions. Great value for the price!

Does not work

Highly recommended. It can be used for cleaning tiles and granite. It also removes cement marks and rust stains too... Value for money. I have been purchasing this since a very long time. It cleans the dirt very fast and gives very good results..... Really happy with the product.
