Economy
  • High cleaning efficiency is maintained over a long period unlike that of solvent-based cleaners
  • No costs for disposal of cleaning solution
  • No costs for transport and storage of hazardous substances
  • No requirement for protective clothing
Operator safety
  • Cleaning solution and microorganisms are completely non-toxic
  • The cleaning agent is pH neutral and therefore does not irritate the skin
  • All substances used are non-flammable
  • No unpleasant odours
Cleaning performance
  • High cleaning efficiency is maintained unlike that of solvent-based cleaners
  • The cleaning solution is heated to a constant temperature of 38ºC which cleans more effectively than a traditional cold cleaner
Environmental protection
  • All substances used are environmentally friendly
  • The biological cleaning system can be used without changing the cleaning agent reducing wastage

How biological parts
cleaning works:

KÄRCHER’s biological parts cleaners are easy to use and can be operated without the safety and environmental hazards associated with solvent-based systems. Unlike solvent-based cleaners and other non-biological cleaners, KÄRCHER’s biological cleaners offer consistently high cleaning performance by using natural microorganisms which break down contaminants such as oil and grease.

When the biological parts cleaner is used for the first time, the cleaning solution is poured through the filter mat releasing microorganisms into the unit’s tank. The solution operates at a constant temperature of 38°C, guaranteeing natural growth of microorganisms in the solution.

A metal strainer in the sink serves as a pre filter for coarse dirt. The filter mat located underneath the strainer retains fine particles larger than 50µm. Substances which collect in the tank such as oil and grease, are broken down by the microorganisms into H²O (water) and CO² (carbon dioxide). Depending on the degree of soiling, a new filter mat should be fitted every 4 to 8 weeks, which introduces new microorganisms into the system maintaining a constantly high cleaning performance.
