Title: How to Remove Pet Urine From Carpet Yourself.
1) If the area is still wet you should first attempt to absorb the dog urine. Leaving it there to dry out will only encourage bacterial growth which causes the smell.
The best method to to remove the urine is to use a wet/dry vacuum. If you don't own one an alternative method is to place several layers of paper towel over the wet urine area and tread on it so as to soak up as much of the dog urine as you possibly can. You may have to repeat this several times until no more dog urine can be soaked up.
Sometimes dog urine accidents have already dried because you did not notice them previously. You can find dried urine spots on your carpet with the aid of a black light. The dog urine stains will fluoresce under the ultra violet light in a darkened room. Hand held black lights are quite inexpensive usually costing between $15 - $25.
Of course, you can always save the expense of a black light. Find the urine spots by using your nose. Just get down on your carpet and sniff and find the offensive urine odors that way.
2) Mix a solution of fifty percent white vinegar and fifty percent water. You must use a liberal amount of this solution to reach the carpet fibers deep down. Work the solution into the carpet with a soft brush (or your fingers) to ensure it penetrates the carpet fibers below.
Then blot the area using the paper towel method above to absorb the vinegar mixture. The vinegar will neutralize the ammonia in the dog urine.
If you own a wet/dry vacuum extractor use it to remove excess moisture.
3) When the area has dried or almost dried sprinkle a good handful of baking soda over the soiled area.
Mix half a cup of 3% hydrogen peroxide with a teaspoon of Dish Soap detergent. Plain liquid dish soap is required. Do not use caustic dishwasher detergent.
4) Slowly pour the 3% hydrogen peroxide and dish soap mixture over the baking soda. Alternatively you can use a spray bottle for the hydrogen peroxide/dish soap solution.
Caution: Do not use Hydrogen Peroxide that is higher than 3% strength (10 Vol) Stronger strengths may bleach a carpet. Then work the baking soda and hydrogen peroxide mixture well into the carpet with your fingers (put on some rubber gloves) or use a brush.
Allow the area to dry completely. Once the area is thoroughly dry, vacuum up the baking soda. A fan or heater can assist drying. Use a hard bristled brush to loosen up the baking soda if necessary.
That's all there is to it. Your carpet will smell fresh and free from urine odor.
NOTE: If you don't have hydrogen peroxide on hand you can substitute it in an emergency for a laundry spray stain remover. Check the bottle. If it says 'Oxy' anywhere on the label then it probably contains hydrogen peroxide.
ALSO: In areas that have been heavily soiled with dog urine you may need the power of a truck mounted professional steam cleaner. At Cleancare of Boulder, we have an amazing process for removing urine from the carpet backing AND the carpet pad.
