Dog Urine Smell and Stain Remover
http://www.dogchatforum.com/dog_urine_odor.htm
Ingredients
Baking Soda
White Vinegar
Liquid Dishwashing Detergent
3% Hydrogen Peroxide
Directions:
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 is to place several layers of paper towel over the wet 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 urine can be soaked up.
Sometimes dog urine accidents have already dried because you did not notice them previously. You can find dried urine patches 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 quiet inexpensive usually costing between $15 - $25
2. The next step is to 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 in with a scrubbing brush to ensure it penetrates the carpet fibers below. Now blot the area again using the paper towel method above. The vinegar will neutralize the ammonia in the dog urine. If you own a wet and dry vacuum extractor use that 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 detergent. Ordinary liquid dishwashing detergent is quite suitable. Put on a pair of rubber gloves and slowly pour the hydrogen peroxide and detergent mixture over the baking powder. Work the dissolving baking soda well into the carpet, first with your fingers and then with a scrubbing brush.
Allow the area to dry completely and then vacuum thoroughly.
If you don't have hydrogen peroxide on hand you could substitute it in an emergency for a spray laundry stain remover. Check the bottle. If it says 'Oxy' anywhere on the label then it probably contains hydrogen peroxide.
In areas that have been heavily soiled with dog urine you may have to repeat the process again.
Important.
Never use ammonia or ammonia-based products on the carpet to remove pet pee. One of the ingredients of urine is ammonia and your dog or puppy may well be encouraged to re-offend in the same area if it detects the smell of ammonia. Many household cleaner cleaners contain ammonia so be sure to read the label.
Caution:
Use only 3% Hydrogen Peroxide
Test your carpet for color fastness in an area that won't show.
