Eco wash itself is basically a compressor wash. In early compressor wash, the water being used in compressor wash are discarded as it is expelled through the engine core exhaust. But in eco wash, a screen type filter is used at the exhaust that recollects the water, filter it and send for re-use again. Thus, this method of compressor wash don’t make wastage of water and hence helps nature to maintain its ecological balance and that is why this type of compressor wash is termed as eco wash.
