It stains a waxed hardwood floor dark brown or black, it's the acid. Vomit if acidic will do the same thing.

It won't do a thing to the polyurethane, just sits there.

I've had both, had a waxed hardwood floor for 12 years and a poly for 10. Only problem with the poly is that it does scratch eventually, even the good stuff, and has to be sanded off and reapplied.

The poyurethane is probably the best, but the wood expands when humid and contracts when dry so the spacing between the boards will separate over time. When a dog urinates the urine will seep between the cracks and stain the wood. Sometimes the wood can be sanded, but after a 5-6 sandings the wood will have to be replaced. If you replace a small section the wood will not match the old wood. Also, when you patch the wood the thickness of the boards may vary from the rest of the floor. If you stain the entire floor to cover the damaged portion you darken the entire room, making it less attractive to perspective tenants.

Replacing a hardwood floor and having it resurfaced will cost approx $8-10.00 per sg. foot. If I have to redo 500 sg. ft. at $8.00 per foot that will be $4,000.00 just for the floor. How does a $400.00 deposit cover this, or the additional vacancy time to get the work done?
