Parts Washers

Innovative parts washers, providing powerful cleaning performance and dramatically lowering waste fluid generation.

Filter Mats

Each mat contains 200 million oil-eating microbes, which can trap particles down to 50 microns.

Degreasing Solution

General or specialist fluid offers highly efficient cleaning of motor oil, bearing grease, cutting and hydraulic fluid, amongst others.

Microbial Booster Fluid

Liquid form of concentrated microbes. Helps fluid stay cleaner for longer, keeping microbes at optimum performance.

How does the ROwasher work?

The ROwasher system constitutes three parts: the parts washer, the microbial filter mat & degreasing solution

Add the the microbial filter mat to the base of the sink, pour the degreasing fluid into the sink so it passes through the filter.

Oil and grease are washed off the dirty part and flow through the Microbial Filter Mat in the sink into the ROwasher's tank.

The Filter Mat contains 200 million oil-eating microbes, trapping particles to 50 microns. For healthy microbes, change this monthly.

Heated to 42°C, the microbes become active in the solution, turning oil & grease into CO² and water – recycling the fluid.
