Pet odor removal

In order to eliminate pet odors, it’s critical to understand the chemistry of pet odors.

Pet urine is the most common cause of pet odors. Urine is composed of water, excess proteins, hormones, inorganic salts, urea, uric acid, and a natural pigment called urochrome. There are three catagories/stages of urine. 1) The fresh accident. 2) In the 2nd stage the bacteria split proteins cause an offensive odor. As urine decomposes it’s PH level turns from acid to alkaline. 3) In the 3rd stage the water completely evaportes and leaves residual alkaliine salt. These salts are hygroscopic which means that they attract atmospheric moisture which causes odor to be released to the air.

In order to effectively decontaminate the urine and accompanying odor, we must remove the dried salts. Since urine is normally alkaline, to remove it we must clean the urine contamination on the acidic side. Therefore an acid rinse is recommended for the initial pretreatment of soft surfaces such as carpet, upholstery, and area rugs. This step suppresses urine related odor, dissolves and dislodges urine salts and fecal deposits.

The two primary options for removing urine contamination are encapsulation and bio-enzymatic digestion. In the encapsulation method, as the name suggests, the solvent surrounds and encapsulates the contamination, rendering it odoless. The bio-enzymatic digestion method involves using an enzyme which digests matter durng the deodorization process.

Complete odor removal in severe urine and pet odor removal may require other techniques including the removal of carpet cushion, and sealing surfaces such as subfloors with a non vapor coating. These methods are extreme and somewhat costly, so it is important to deal with the situation early on to minimize your cost. Some pets, especially cats, are attracted to their smell and will continually go back to the same area, so resolve the situation early.
