Safety first: Wear gloves and eye protection when handling brine and cleaning chemicals.

• Empty brine tank: Scoop out salt and pump or vacuum out brine. Dispose of according to local regulations.
• Clean tank: Scrub the inside of the brine tank with a mild bleach solution (e.g., 1/4 cup household bleach per gallon of water). Rinse thoroughly.
• Sanitize system: Follow Aquabion's procedure for sanitizing the softener, typically involving adding a measured amount of bleach to the brine well and running a regeneration.
• Refill with clean salt: Use high-purity water softener salt and avoid contaminants.
