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.
Gets the black spots up quick and the dog drool.
The product was easy to apply, but couldn’t completely remove a slime stain. The stain penetrated a stained finish with poly top coat. I soaked a paper towel and left it on the stained surface for 24 hrs. The stain faded, but is still present.
Tannin Remover is intended to be used on untreated, oiled and waxed surfaces. As you experienced, it will not be as affective on a poly coated surface.
We just moved into our new home with white oak flooring and Rubio Monocoat white applied. Within weeks our very large dogs had a few issues a couple of nights and defecated on the oak. I ordered the tannin remover and gave the spots several applications and it worked like a miracle! The **** stains are gone. You cannot even tell where they were. I ordered the small bottle (no sprayer) and just applied a small glob, rubbed it around with my finger and waited for the results. The sprayer would be ideal but my method did work.
