Knowing how to clean carpets is not a science, but to keep your carpets looking newer longer there are several factors to take into consideration such as time and expense, type of carpet, degree of stain and soil, and drying time. Discover which carpet cleaning methods are optimal for your situation.

The five methods of carpet cleaning most commonly utilized are hot water extraction/steam cleaning, rotary shampooing, dry extraction, dry foam extraction, and bonnet/absorbent-pad cleaning. For do-it-yourself residential carpet cleaning, the hot water and dry extraction methods are the best choices. Although dry foam extraction may be performed by a do-it-yourself cleaner, the results are often marginal. Bonnet and rotary shampooing are effective, but they're not recommended for residential use unless done by a professional.

Regardless which method you choose be sure to carefully follow the directions given by the product and machine manufacturers as closely as possible.

Basic Steps for at Home Carpet Cleaning 

1. Move everything off the carpet.
   
   
2. Vacuum with your regular vacuum cleaner
   
   
3. Pre-treat stains and heavily soiled areas with either a commercial or homemade carpet stain removal solution, and let the solution set for at least 10-20 minutes, then either manually or mechanically agitate the solution to bring dirt and contaminants to the surface.
   
   
4. Mix and apply the cleaning solution.
   
   
5. Work the cleaning solution into the carpet, and then thoroughly extract it and any moisture.
   
   
6. If placing furniture on a damp carpet, put plastic pads, foam disks, or aluminum foil under the furniture legs to avoid possible damage and staining.
   
   
7. Use air movers (fans, air conditioner or heater, and open windows) during and after cleaning the carpet to avoid mold growth and to speed up drying time. If at all possible, don't clean the carpet on really humid or rainy day.
   

You can also steam clean the carpet using plain water or a solution made from 1 cup white vinegar and 2-1/2 gallons of water, or a mixture of 3-4 tablespoons of mild liquid soap and at least one gallon of water, but this mixture shouldn't be mixed to vigorously, as you do not want the suds to clog your machine
