While dog ownership is rewarding, most dog owners have house-training horror stories involving urine accidents on the carpet or hardwood floor. The odour can linger long after the stain has gone, causing an unpleasant scent for homeowners and visitors. If you treat the stain while it is fresh, the odour is less likely to linger in the floorboards of your house, but this is not always possible. Left untreated, dog urine stains can soak deep into floorboards, causing constant odour.
Place paper towels on top of the urine stain, and blot up as much liquid as possible.
Sprinkle the stain with white vinegar, and rub it in with a damp rag or a soft scrubbing brush.
Rinse the vinegar from the floorboards with warm water, and blot with paper towels. Let the floorboards dry.
Spray the dry stain with an enzymatic pet stain and odour remover. Rub gently with a damp cloth, and let the cleaner dry. Repeat if the odour remains.
Sand the floorboards using sandpaper or an electric sander to remove the stained surface of the wood.
Re-finish the floorboards using a shellac-based primer.
If the stain is too deep to sand out, remove the stained section of floorboard. Replace with a new floorboard.
Check with the manufacturer before using any commercial cleaning products on hardwood, because some chemicals can cause discolouration or damage the surface of the wood.
