Being a dog owner means that you have most likely had to deal with getting dog urine smells out of your floor. Unfortunately, dogs and especially puppies can have accidents in which their urine leaves a nasty smell that is difficult to get rid off. Luckily, cleaning dog urine smells from a wood floor is not impossible. According to the University of Nebraska Lincoln, dog urine on wood floors is usually only in the floor's top layer. This means you can fix the problem.
Soak up the dog urine as soon as possible. The sooner you soak up the urine, the less chance it has of soaking into the floor, allowing the smell to set. Use paper towels or cotton towels to soak up the dog urine until they don't absorb any more. Each time you apply the towels stand on them, as the pressure will help soak up the dog pee. Remember to just blot the urine and not rub it, as rubbing it can make the problem worse, according to Paw-Rescue.org.
Use water and a sponge to rinse the area of your wood floor with the dog urine smell. Repeat the rinsing process a few times with warm water and use a towel to blot the area between each rinse. This can help remove the urine and thus the smell from the wood floor.
Apply a mixture of 1/2 water, 1/2 vinegar to the dog urine smell using a sponge. White vinegar is an inexpensive product that kills bacteria and helps remove dog urine smell. Let it stand for a few minutes before soaking it up with a paper towel. Apply the vinegar mixture again, this time placing paper towels under something heavy and leave the vinegar to soak the stain for a few hours.
Apply a neutralising product according to package directions to get rid of the dog urine smell. There are a number of odour-neutralising products on the market that are formulated to get rid of dog urine smells. A neutraliser helps break down the smell and eliminate it.
Re-finish the section of wood floor with dog urine smell. This is a last resort, as it can be expensive. Unfortunately, if vinegar and a pet-odour neutraliser fail to remove the dog urine stink, re-finishing the floor is the only way to get rid of the smell. You will need to sand the top layer of wood to remove the damaged wood, especially if the urine has caused a dark stain. After sanding the affected area, apply a varnish that will seal the wood. A sealant will help prevent future accidents from getting into the wood and causing a smell.
