How To Clean Pet Stains from Concrete
Even sealed concrete may be porous to a certain degree, and will absorb and retain staining materials and odors. If your pet or another animal has an accident, not only does the visible residue of the stain need to be removed, but the staining material needs to be broken down at the chemical level to prevent repetitive staining. Follow these basic steps to alleviate current stains and help prevent subsequent mess. Use disposable tools, and keep plastic bags on hand to discard contaminated materials. Remember, that concrete types and sealants can vary, and cleaning materials and techniques should be tested on a small area before using on a wider area.
If there is any bulk material, remove and discard using a paper towel. For standing liquid, pour an amount of kitty litter on the stain that will adequately absorb the liquid. Once the excess liquid is absorbed, remove and discard the soaked kitty litter. Next, use a product with enzymes or bacteria designed to break down urine and fecal matter at the chemical level. Apply according to the manufacturer's directions; for convenience, many of these products, which are readily available at pet stores and medical supply stores, are packaged as sprays. If you feel it is necessary, you can follow with a clean water rinse and light scrub with a nylon bristle brush. Use clean newspapers to absorb any excess water, and allow the affected area to dry thoroughly.
Caution: Never mix cleaning agents or chemicals, the result can be dangerous or deadly. Before cleaning, always test the agent on an inconspicuous location to determine its suitability and to make certain it does not damage the material. Wear appropriate clothing such as gloves and protective eyewear, and work in a well-ventilated area. Accidental inhalation or ingestion of cleaning agents can be hazardous and even fatal, particularly to pets and children.
