Visible pet stains and a pungent urine odor are cause enough to get your carpets cleaned regularly, but let's not forget about the everyday dirt, pet dander, allergens, and insects that are brought into your home everytime your pet comes in from outside. As long as your pet hasn't been rolling around in the mud, unfortunately you will not visibly see these microsopic contaminants. These contaminants will absorb into your carpets, furniture, rugs, tile grout, and mattresses. Over time, it will cause visible soiling, but more importantly, a less-than-healthy living environment for you and your family if not treated. Sierra ProClean typically recommend a professional steam cleaning and extraction at minimum of once per year, though our clients with pets should have their carpets cleaned every 6 months, if not more frequently, to control stains, odors, and allergens.
