If you're sensitive to cigarette smoke, you might find that you'll breathe easier after you hire a company to get those harmful chemicals out of your carpet. So, in addition to getting rid of dirt, another important reason to clean your carpet is to get rid of pollens, fungus, bacteria, chemicals and the tars and residue from tobacco smoke. First, I'll explain dry cleaning. Many people believe that dry cleaning your carpet is like dry cleaning your clothing. This is not true.
All carpet cleaning methods use water in one form or another.
This method can leave a residue in your carpet, which is one reason dry foam is not very effective. The dry-chem method is similar to dry foam. The major difference is that when dry-chem is used, the company sets a large cotton bonnet on your carpet. Using a machine, the bonnet spins from side to side, absorbing the dirt that's in the carpet. After the bonnet is saturated with dirt, they apply another cotton bonnet.
