excellent. the stains from the bathroom cleaner looked terrible. the tannin remover was easy to use and got rid of almost all of it.
Removed black tannin marks from my countertop after leaving a carbon steel pan on the countertop over night (not hot) during a high humidity day. I was worried I’d have to have it sanded and refinished, but this did the trick perfectly in two applications. Took about 20 minutes all together, and you’d never know there was a stain on my countertop! I took a clean cloth, dipped it in the bottle, then applied directly to the marks I wished to remove. A little goes a long way. I bought the 100 ml bottle, and it would cover this accident several times over.
I was told by a flooring representative that our stain situation was the worst of the worst, and that our best bet was sanding our entire floor. Several squirts and a few minutes later and most of the stains were gone. This did not work as well with the pigmented stains, but overall, I am very happy with the results.
Worked very well
This product really works. When the initial stain appeared, I was met with dread but was thrilled to find out a product exists to help such mistakes! It took a few rounds of application but the end result is exactly how it used to be.
