Water-based parts cleaning became practical with the introduction of
bioremediation: the use of living organisms to turn hazardous materials into
Chemists and engineers put microbes to work in an industrial setting by
creating a parts washer that combines a powerful cleaning fluid with
bioremediating microbes. The fluid lifts grease and dirt from the part and
flushes it into a reservoir. Here, the microbes, thriving in a tailored
environment, digest the grease. The components of the digestion process-CO2
and water-evaporate into the air.
Early bioremediating parts washers had their shortcomings. Some lubricants
were difficult to clean and the bioremediating process sometimes produced a
barnyard odor. The microbes themselves often succumbed to temperature
Today's state-of-the-art bioremediating parts washer has corrected these
problems. New designs combine fluid, filter, pump, heater, and the safe-but
voracious-microbes in a closed-loop system that requires little maintenance.
Its cleaning efficiency is comparable to parts washers using premium
solvents. When used properly, there is nothing to haul or skim. The fluid
cleans the part, and the microbes clean the fluid. For this reason, the
fluid remains at peak efficiency and need never be replaced-just topped off
to replace fluid lost to normal evaporation.
The latest generation of surfactant fluids can remove even fifth-wheel
grease and other lubricants that defy ordinary water-based cleaners. New
strains of robust microbes can thrive in a wide range of temperatures. The
only maintenance required is the monthly replacement of a filter mat that
captures particulates and supplies a fresh colony of microbes. Disposal of
the filter mat usually may be as ordinary solid waste.
Thus is the parts washer once again the simple, easy-to-use, cost-effective
machine that does its job with little attention. And at little or no cost to
