While there is no standardized carpet cleaning frequency for every home, we recommend regular extraction, before your carpet becomes excessively soiled. Some areas may require monthly extraction, while limited-use areas only may require a yearly extraction.
The following should be considered when cleaning carpet:
Following is the recommended carpet cleaning procedure for the care of residential carpet products:
Prevacuum the area to be cleaned, taking care to remove as much dry particulate (insoluble soil) as possible. Water extraction is performed to remove water-soluble soil that cannot easily be removed with daily vacuuming. Detergents, used in the carpet cleaning process, attempt to emulsify these non-water soluble particulates, thus reducing carpet cleaning effectiveness.
Following thorough vacuuming, apply an alkaline prespray detergent or odosolv directly to the face fiber. Prespray detergents typically require 8-10 minutes of dwell time to begin emulsifying and suspending soil. Extracting the solution before allowing adequate dwell time will reduce carpet cleaning effectiveness.
Agitate the area with a pile rake or mechanical agitation. NEVER USE A ROTARY BONNET for mechanical agitation. Agitation will assist the detergent solution in lifting soil from the fiber and dramatically enhance carpet cleaning results.
Extract the detergent solution and attached soil particles using an extractor with fresh water only. Do not use a detergent solution in the extractor tank. Many of these solutions leave oily residues or detergent residues that expedite resoiling.
After thoroughly rinsing, continue to extract the area using "dry" strokes (no water injection) until suitable moisture removal is attained. Under no circumstance should any carpet product be allowed to remain wet for more than 12 hours.
Other considerations:
It is not uncommon in heavy soiling situations for soil to reappear within 24 hours following drying. These instances almost always can be attributed to excess dry soil left in the pile fiber, prior to applying prespray. If soiling reoccurs, vacuum the area using multiple vacuum passes and repeat the above procedures. If soiling returns after the second extraction, select a dry extraction compound such as Host or Capture. Apply the compound to the (dry) carpet pile, agitate, and then vacuum.
Soiling that reoccurs more than 24 hours following carpet cleaning often may be attributed to detergent residues that were not adequately rinsed. Evaluate detergency by pouring water onto pile fiber and briskly agitating with a spotting brush. Look for foaming or other signs of detergent residue. If detergent is present, continue to extract these areas until detergent is thoroughly rinsed. In severe situations, an acid rinse, such as white vinegar, may be applied as a prespray or added to the extractor rinse tank to neutralize detergent residues.
