The Hard Facts About Soft Washing

What You Don't Know About Water Tower & Tank Cleaning Could Cost You.
After twenty eight years of service, we have seen and experienced many different methods of cleaning water storage tanks & towers that involve mildew removal.

It seems most companies' concept in the tank cleaning business is to just "blast away" the grime and mildew stains. With water storage tank paint jobs costing hundreds of thousands of dollars, you want to yield the longest possible time between painting applications.

Our "Soft Wash Method" uses less than 1,200 psi (avg.800 - 1,200 psi) water pressure. For a comparison example, most self-serve car wash bays operate at 1,100 psi to 1,500 psi.

No high pressure washing or blasting is required to remove ugly mildew stains from the tank's painted surface.

This Soft Wash and low psi method flushes off dirt, grime, and mildew stains while minimizing the high pressure washing damage risk to yield a long life for tank paints.
