CCT CCT Drying & Post-Cleaning Procedures

Question 1

What is the recommended maximum drying time for carpet after hot water extraction cleaning under normal conditions?

Accepted Answer

6 to 12 hours

Answer

Properly cleaned carpets should dry within 6 to 12 hours under normal conditions with adequate ventilation; longer drying times significantly increase the risk of mold and mildew growth.

Question 2

Which piece of equipment is most effective for accelerating carpet drying time after hot water extraction?

Accepted Answer

An air mover or axial fan positioned across the carpet surface

Answer

Air movers (axial fans) create high-velocity airflow across the carpet surface, dramatically accelerating the evaporation process and reducing overall drying time.

Question 3

At what indoor relative humidity level does mold growth become a significant concern during the carpet drying phase?

Accepted Answer

Above 60% relative humidity

Answer

Relative humidity above 60% creates conditions favorable for mold and mildew growth, making active humidity control a critical component of the carpet drying process.

Question 4

Why should customers be advised to avoid heavy foot traffic on freshly cleaned carpets?

Accepted Answer

To allow fibers to dry fully and prevent re-soiling from shoe contaminants being pressed into damp fibers

Answer

Walking on wet carpet transfers soil from shoes into damp fibers and can distort pile structure, undoing the cleaning and causing accelerated re-soiling.

Question 5

What is the function of a dehumidifier used alongside air movers during the carpet drying phase?

Accepted Answer

To remove evaporated moisture from the air before it can be reabsorbed into the carpet or building materials

Answer

Dehumidifiers extract evaporated moisture from the ambient air before it can be reabsorbed by the carpet or surrounding building materials, significantly accelerating total drying time.
