Servicing Sonoma County and the North Bay Area.
There are just two reasons why spots come back after your carpets have been professionally cleaned.
1. The spot or area had such heavy buildup and or was never picked up properly when the spill originally occurred that a second cleaning is needed. This occurrence is called wicking. Wicking is the process where the soil that is in the carpet backing or even padding works its way to the surface in the drying process after the carpet has been cleaned. There is treatment available for wicking but cleaning the carpet is first recommended to find out what areas need more attention.
2. A residue left behind from a product that was used to clean the spill now attracts dirt to the spot or area making the spot "re-appear".
