Urine stains leave behind an unpleasant, lingering odour and make your mattress appear unsightly. If your dog urinates on your mattress, clean it immediately to prevent the urine from seeping into the material. Get dog urine out of your mattress with items already in your home, instead of purchasing commercial cleaning products. After you remove the dog urine, dry the mattress properly to prevent mould and mildew from growing.
Blot the dog urine with paper towels to remove as much as possible from the mattress. Avoid rubbing, as doing so spreads the dog urine.
Apply baking soda over remaining dog urine, completely covering it. Baking soda absorbs moisture and odour. Let the baking soda sit for one hour, and then vacuum it off the mattress.
Combine two parts vinegar and one part water in a spray bottle. Spray the area where the dog urinated.
Move the mattress outdoors into the sunlight. Direct sunlight helps to disinfect and dry the mattress. If you are not able to move the mattress outdoors, dry it with a portable fan.
If you still notice an unpleasant odour on your mattress, try a commercial enzyme cleaner designed to eliminate dog-urine odour.
Do not put bedding on the mattress until it dries completely, as doing so can cause mould or mildew to grow.
