what are you trying to remove or elminate?
if its urine you CANT remove it since its soaked in the wood:(
The BEST you can do is scrub well, with whatever you want, then let dry
sand and at least 2 coats of outdoor polyurethane.
you cant remove odors from wood just seal them in!
Outdoor poly since if it later gets wet the odor will NOT come back!
this is the only effective way to take care of odors in wood, wether
they are smoke urine etc and is what the fire restoration comapnies do.
follow the directions and its 100% effective forever!
