Water in its Purest Form has Powerful Cleaning Abilities

Ultra pure water naturally absorbs dirt and air pollution particles commonly found in ports and urban areas, whereas tap water, which contains minerals and dirt, does not.  


Furthermore, when used in a simultaneous rinsing method with a CrystalWash spray brush, dirt is flawlessly knocked off surfaces and impurities are removed leaving a perfectly spot-free surface.   


Washing down requires considerably less detergent -- only the most persistent, greasy stains require a spray of soap.

In the long term, regular use of ultra pure water significantly slows the natural progression of clouding and fading of surfaces, and subsequently reducing the need for polishing and buffing -- which cause micro-scratches -- resulting in lasting durability of shiny surfaces.

CystalWash recommends the occasional application of a UV-Protective polishing/non-beading liquid to support this brilliance.


Regular rinsing down with a CrystalWash spray gun removes impurities that accumulate on a daily basis or on very salty sailing days without requiring the hours typically needed to wipe down. 

For example, when using CrystalWash to rinse down a 25m motor yacht with a fly bridge, the task can be completed by just one person in about an hour -- including rinsing the hull.  And, after an hour of natural drying (at approx. 25X C) and no wiping, you can be certain to have impeccable surfaces without any trace of streaks or water marks.
