CCT Odor Control & Deodorization 3

Question 1

How long should enzyme-based deodorizers typically be allowed to dwell for maximum effectiveness?

Accepted Answer

As long as the manufacturer recommends—often 10–30 minutes or longer for heavy contamination

Answer

30 seconds to 1 minute only

Answer

Exactly 5 minutes in all cases

Answer

Overnight only; shorter dwell times are ineffective

Question 2

Which of the following odor types would NOT be effectively treated by enzyme digesters?

Accepted Answer

Smoke and fire odors

Answer

Pet urine odor

Answer

Food and beverage spill odors

Answer

Biological mold and mildew odors

Question 3

What is a critical safety precaution when using ozone generators for carpet odor treatment?

Accepted Answer

Keep all humans, pets, and plants out of the area during treatment as high ozone is harmful

Answer

Apply with high-pH cleaning solution only for best results

Answer

Ensure the treated area is occupied to monitor effectiveness

Answer

Run the ozone generator while the HVAC system is operating to distribute ozone

Question 4

Why do urine odors sometimes return after an initial successful treatment?

Accepted Answer

Urine salts rehydrate with ambient humidity and release odor compounds again

Answer

The deodorizer used was too alkaline for the carpet fibers

Answer

The carpet fiber type rejected the deodorizer molecules

Answer

Too much water was used during the extraction process

Question 5

Which of the following is a 'counteractant' type deodorizer?

Accepted Answer

A product that chemically pairs with and neutralizes specific odor molecules at the molecular level

Answer

A product that uses live enzyme cultures to digest waste

Answer

A product containing fragrances designed to mask odors

Answer

A product that creates a physical polymer barrier around carpet fibers

Question 6

When treating a carpet for mold odor, what must be addressed in addition to applying a deodorizer?

Accepted Answer

The actual mold growth must be eliminated and the moisture source corrected, or regrowth will continue

Answer

The carpet color must be restored with a color brightener

Answer

The carpet must be dried to exactly 75% relative humidity

Answer

An acid rinse must be applied to neutralize residual alkalinity

Question 7

What does the term 'off-gassing' refer to in the context of carpet odors?

Accepted Answer

The release of volatile chemical compounds from carpet materials or contaminants into the air

Answer

The process of removing gas from compressed air lines in cleaning equipment

Answer

A method for purging enzyme digesters after treatment is complete

Answer

Ventilating a room after hot water extraction to remove steam
