Odour & Biofilm Control
Today, visible cleanliness may not reflect the reality
-
Odours indicate underlying biological contamination
-
Biofilms protect pathogens from normal cleaning
-
Persistent smells reduce perceived hygiene and trust
You’ve deep-cleaned the kennel, washed the mats, and disinfected the water bowls — but the smell comes back. Whether it’s a grooming van, barn aisle, litter area, or shelter intake room, persistent odours usually signal that microorganisms are still present and protected within biofilms. A biofilm, different to a free-floating pathogen, is a protective layer of microorganisms (such as bacteria or fungi) that stick to surfaces and surround themselves with a self-produced matrix, making them much harder to remove or kill than the free-floating microbes. For example, in pet water bowls, biofilms form from the microorganisms, food debris, and saliva that combine to cling to the plastic, metal or ceramic surface. Beyond looking gross, these biofilms cause bad breath, periodontal disease, and can hinder nutrient absorption.
​
Traditional detergents and surface disinfectants often remove visible dirt but fail to penetrate biofilms, allowing bacteria and fungi to survive, multiply, and continue producing odour-causing compounds. This creates a cycle of repeated cleaning without real microbial control.
How Clean Play helps:
Biofilm & Organic Load Reduction
-
Disrupts biofilms instead of masking odours
-
Reduces microbial load at the source
-
Improves environmental hygiene, not just smell
​
The SaniChest’s cold plasma technology targets microorganisms at a molecular level, breaking down biofilms and neutralizing odour-causing microbes rather than simply covering smells with fragrance or relying on repeated chemical use.
Primary Use Case - Avery
Zoo Operations Manager
Avery manages a busy zoo with over 50 species and high visitor volumes. Despite daily cleaning with disinfectants, the facility struggles with persistent odours in certain enclosures. Avery knows that odour isn’t just unpleasant — it affects the guest experience, visitor perception, and animal welfare. More importantly, it can signal that microbial contamination is still present, even after cleaning.
Industry Data & Operational Evidence
Odours are caused by microbial activity and organic waste breakdown, not just dirt. Persistent odours result from bacteria and fungi producing volatile compounds during the decomposition of organic matter.
Biofilms protect bacteria from disinfectants and make them significantly harder to eliminate. Biofilms can increase resistance to disinfectants and antimicrobials by up to 1,000 times compared to free-floating bacteria.
Standard cleaning and disinfection often fail to remove biofilms from surfaces. Biofilms adhere strongly to surfaces and are not easily removed by routine cleaning or chemical disinfectants alone.
Persistent odours in animal facilities are indicators of ongoing microbial contamination. Environmental health guidance notes that recurring odours usually reflect biological growth and inadequate microbial control.
