Re: Problem: Refinishing Pine Hardwood Floor

Try using oxalic acid (wood bleach) on it. It may lighten the darker spots. Sherwin Williams has it, big boxes didn't last I checked. It comes as crystals that you mix with water. Oxalic Acid does not whiten the floor as some two part bleaches do, so you can still achieve a natural floor color.

Will give the acid a try; nothing to lose. At this point I guess the alternative is a new hardwood floor over the original floor.

We can probably come with some other things to try, but I think oxalic acid would be my first choice.

Tried Sherwin Williams for the oxalic acid, they only sell a wood bleach that contains oxalic acid. Will try some smaller hardward stores today for the crystals / powder. One question, if I try this on a small area, how do I neutralize the acid; I don't want to leave water stains on the floor. Thanks.

Typical -- newer employees don't seem to know they sell it. I've had to ask for a manager to find it before

Directions for this product say to neutralize with 1 tablespoon baking soda per gallon of water. I always recommend following the directions so make sure to read the label for the product you use.
