Soft Wash Mix Calculator

Below is a calculator that shows what settings on your proportioner valves equate to final output soft wash mix percentages.

Please Note:

  • 1. Your water and SH tanks must be plumbed EXACTLY the same (same hose length/diameter, same connection types).
  • 2. This calculator does not account for surfactant addition, which may slightly affect the final output.
