Pet stains not only are unsightly, but also often result in less-than-pleasant odors.
A simple and effective way to get a pet stain out is to use a solution of 2 tablespoons of Spic-n-Span in 1 gallon of warm water working the solution into the area with a cloth or sponge.
Next, rinse the area with 1/2 cup of white vinegar in 1 gallon of warm water. This will help neutralize the detergent and prevent it from attracting dirt. Finally, blot the area with a dry towel to remove any excess dampness.
Hard-hit areas might require professional steam-cleaning, replacement of the pad below, or even a bleaching of the concrete or wood substrate to kill the odor-causing bacteria.
