Hardwood floor restore. Non-toxic, safe for pets, children, and you! Sometimes you get a not so nice surprise under your area rugs. We were on vacation and came home to find our geriatric cat had decided the litter box was too much trouble.
This lovely mess was waiting for us.
I first swept and wiped the area down. Then I poured peroxide over the blackened areas, straight from the bottle and let it sit for 15 minutes. You can scrub it around with a soft brush during this time, I did not.
