Car Washes Do Not Provide Bacteria Level Testing


Driving into a traditional car wash, a damp floor, moulds on the walls and ceilings are usually the first things you would notice when you get out from your car. Are we really cleaning the car interior, or are we just allowing cross infection of bacteria happen? Traditional car washes rarely clean or sanitize tools, but they often re-use cleaning towels to clean or dry the cars. Do you really trust their disinfecting result?


Common Problems that a Bad Car Wash Job Can Cause

  • Car may be sprayed with acid cleaner to remove grime.
  • Only focus on dirt and dust, instead of eliminating the invisible germs and moulds.
  • Re-use towels, bringing the germs and dirt to the car of the next customer.
  • Tools are often not cleaned and sanitized, sanitation is poor.
  • Using common vacuum cleaners that could cause secondary contamination, and the allergens and pollutants still remain in the car.
  • Do not have any standard to evaluate the effectiveness of cleaning and sanitization.

Professional Testing Device


We adopt Hygiena SystemSURE Plus™ Luminometer to perform the ATP Cleaning Verification. The device gives a numeric measurement of organic material (ATP) on a surface, measured in relative light units (RLU). The more ATP presents on a surface, the higher the RLU measurement. This method is recommended by Centers for Disease Control and Prevention (CDC).


The detection of Adenosine Triphosphate (ATP), the universal unit energy in all living cells, determines if surfaces are truly clean. For those sensitive areas like homes, schools, nurseries and, health institutions (i.e. clinics), ATP Cleaning Verification provides a quick way to detect microorganisms. By collecting samples from the environments, and measure the ATP level, it gives a direct measure of biological concentration in the environments.
