I have a contractor who used Oxalic Acid (1 pint to a 1 gal) to bleach out some stains in a room. He then came back and buffed in a coat of oil. After 24 hours the floor that was treated had not dried completely . Unfortunately(?) he was able to get a coat of poly on the top and that has not dried completely either. I recommended he wait another day. Anyone have experience with Oxalic Acid?
