CCT Odor Control & Deodorization

Question 1

What is the primary purpose of a deodorizer in carpet cleaning?

Accepted Answer

To eliminate or neutralize odor-causing compounds

Answer

Deodorizers are specifically formulated to eliminate or neutralize the chemical compounds responsible for unpleasant odors.

Question 2

Which type of odor is best treated with an enzyme digester?

Accepted Answer

Organic odors such as pet urine or food

Answer

Enzyme digesters contain biological enzymes that break down organic matter—proteins, uric acid, etc.—that cause odors from pet urine, food, and other organic sources.

Question 3

What is a 'masking agent' in the context of odor control?

Accepted Answer

A substance that produces a pleasant scent to cover up an odor

Answer

Masking agents work by covering up the unpleasant odor with a stronger, more pleasant fragrance rather than eliminating the odor source.

Question 4

At what approximate pH level do most enzyme-based deodorizers work most effectively?

Accepted Answer

pH 6–8 (near neutral)

Answer

Enzyme-based deodorizers generally work best at near-neutral pH levels (6–8) because most biological enzymes are most active under neutral conditions.

Question 5

Which chemical process does ozone (O3) use to neutralize carpet odors?

Accepted Answer

Oxidation

Answer

Ozone (O3) is a powerful oxidizing agent that reacts with and destroys odor-causing molecules through the process of oxidation.
