Biological parts cleaners
Microorganisms instead of solvents
Conventional washbasins use solvents and release chemical vapors that can endanger the health of employees. These devices may only be operated with protective gloves and respiratory protection. So-called biological parts cleaners are the alternative: the Mewa Bio-Circle, for example, uses a cleaning fluid with microorganisms that biodegrade oils and fats.
But what about the cleaning power of such a "mild" liquid? "Comparative tests have shown that the Mewa Bio-Circle works particularly well on oils and greases, as well as on burnt-on cracks," reports Daniel Krause, assistant to the management of the service provider Mewa at the Weil im Schönbuch site. The aqueous, pH-neutral cleaner then unfolds its full cleaning power. Equally good results should be achieved with soiling caused by salts, sugar and dust. The parts to be cleaned should be made of stainless steel, steel, aluminum or non-ferrous metal.
However, the biological parts cleaner is not suitable for varnishes, paints, resins, silicones and biocides. These substances must not enter the system as they are harmful to the microorganisms. In these cases, a conventional cold cleaner is recommended. cs
