Common carpet cleaning methods:
Steam cleaning (also known as hot water extraction): The most universally used carpet cleaning technique. This process typically involves spraying a solution of warm or hot water and a cleaning agent into the carpet, then extracting it all with a powerful vacuum. This can be a truck-mounted system or a portable unit. The truck mounted system ensures the dirt is removed outside the home. A downside to hot water extraction cleaning is a long dry time, which typically ranges from four to 10 hours, depending on the carpet type and the humidity level in the home.
Bonnet cleaning: A low moisture cleaning method which some prefer because there is less of a chance for mold and mildew. The bonnet method consists of a round cleaning pad that fits like a cap over a rotary brush to help loosen dirt from the carpet. While the top one-third of the carpet is cleaned, soil which has settled to the bottom of the pile remains behind. This cleaning method should be viewed as a temporary measure between more intensive cleanings.
"Dry" carbonating extraction: Uses carbonation to create effervescent bubbles, which lift dirt from the carpet before extracting it with a strong vacuum. Though frequently referred to as a "dry" method, it actually does use water, but requires just a fifth of the water needed for traditional steam cleaning, Some companies may heat the solution up before applying it to give it more reaction to the carpet versus using plain water.
Angie's List carpet cleaning advice: Taking care of your carpet will help extend its life. Well-maintained carpet can last 10-15 years.
What does the manufacturer recommend? While most carpet types can withstand any of these cleaning methods, it's important to follow your carpet manufacturer's recommended method. Some manufacturers will not honor the carpet's warranty to cover damage if their specified method is not followed.
Act fast: The longer a stain sits in your carpet, the hard it is to remove it. Some cleaning products can actually make a stain worse if not used properly - so be sure to call a professional.
Clean regularly: To keep your carpets cleaner longer, vacuum them regularly yourself with a good, household vacuum cleaner and have them professionally cleaned by a qualified and reputable company at least once a year and in accordance with your manufacturer's instructions. Clean more often if you have pets or heavy foot traffic.
Is your carpet loose? Consider getting your carpet stretched if it's showing signs of being loose. A loose carpet will wear faster because the fibers overlap and rub together with the dirt buried in them, which acts like sand paper.
Homeowners can rent or buy carpet cleaning equipment, but these machines usually aren't as effective as professional cleaners. Professional carpet cleaners have access to commercially available equipment and cleaning supplies.
Angie's List tips for hiring a professional carpet cleaner:
What's the cost? Professional carpet cleaning costs typically start at around $79 for a small area and go up from there, depending on the size of your home and the type of cleaning you choose. Plus, stairs and hallways are generally not considered part of a room. Most companies will offer a free in-home estimate. Avoid the temptation of offers from companies offering super-cheap cleanings - for example, a $49 whole-house cleaning. Generally speaking, these deals are too good to be true.
Ask about certification: Only use carpet cleaning companies who can show certification from the Institute of Inspection, Cleaning and Restoration (IICRC), which most manufacturers require, and are insured and bonded.
Obtain a written contract: Before any work is done, obtain a written contract with the total prices and statement of guarantees that the cleaning company offers. Most reputable companies will return if carpet stains show back up after they leave - so ask about any guarantees before you sign a contract.
