The method we use for carpet cleaning is hot water extraction, commonly referred to as steam cleaning. Stanley Steemer's exclusive hot water extraction method removes the toughest, deepest dirt safely and gently. Hot, soft water and a specially formulated cleaning solution are injected deep within the carpet fibers.

Ask about cleaning techniques. Hot-water extraction, sometimes called “steam cleaning,” is the most common technique professional carpet cleaners use and the method recommended by many carpet manufacturers.

“In most cases, consider [properly] disposing of any cleaning solution if it has not been used for more than two years,” says Wilson.

That said, there is no guarantee that professional carpet cleaners will be able to remove each and every stain from your carpet, particularly if we haven't seen the carpet. Or it may take more than one professional carpet clean to completely remove long-term stains from your carpet.
