Carpet Warranties (Deep Cleaning - Continued )

b. The alkalinity (pHi of the detergent solution should be 9.0 to 10.0. The pH should never be any higher than 10.0; it may be lower than 9.0, but cleaning will usually be less effective.

c. You may wish to express your concerns to the cleaning company you are considering using, about over-wetting your carpet. A situation of this nature can be avoided with equipment in good working order with a strong vacuum system. Plan to stay off the carpet for 8 to 12 hours after the cleaning to allow the carpet to dry free of foot traffic.

Light Surface Cleaning

Dry compound cleaning utilizing semi-moist powders, that are worked into the carpet and extracted with a strong vacuum system. Examples of these compounds are Capture® and Host®.

Bonnet cleaning which utilizes a carbonated solution. An example of this type of cleaning is the ChemDry system.

Foam cleaning. The detergent is turned into a foam, brushed into the carpet and then extracted with a strong vacuum system. An example of this system is the Von Schrader cleaning method. (Avoid aerosol foam carpet cleaners such as those available in grocery stores.)
The three methods reflected above are adequate for light surface soil, however, once the carpet has become appreciably soiled and has been in use for an extended period of time, a deep cleaning should be utilized. It should be understood that with the dry compound, bonnet and foam methods, traces of the cleaning agent remain in the carpet. It should also be understood that after employing these methods a few times, a switch should be made to the hot water or steam extraction method. This is not to say that the hot water or steam extraction method cannot be used initially.
