Worked great! And Manny was fantastic at giving me tips on how to use it!
It takes the dark spots off our wonderful new floor.
What an amazing product. We had two dark ring stains of zinc oxide on our island and after my wife spoke to Jeff, we used the tannin remover this evening and it worked wonders. The stains are gone after only 10 minutes of letting the tannin remover sit on the stains and there was no discoloration or fading of the oil finish. Amazing company, amazing product, and even better service. We can't say enough good things about Rubio Monocoat.
