Step 1: Clean with the detergent

  1. Empty the tank and add 1 ounce of concentrated detergent solution to the fresh water tank for every 4 gallons of tank capacity.
  2. Fill the tank with water and run the diluted detergent through each faucet, shower, and water outlet for 1 minute or more.
  3. Empty the tank and rinse the faucet lines and tank by running fresh water through them.

Step 2: Sanitize the water

  1. Shut off incoming water line and prepare a solution of 2 ounces of product per 8 gallons of water.
  2. Apply or circulate solution to wet all surfaces, allowing it a minimum contact of 60 seconds.
  3. Drain the solution and return to service by reopening incoming water lines.

The treatment is effective even in hard water and will not leave grit or soap scum. Not a drinking water additive.
