Cleaning & Maintenance

Cleaning Exterior

To clean the exterior, use a mild, non-abrasive household type cleaner mixed with warm water. Apply by using a damp cloth that you soaked in the cleaning solution and wrung out. Do not expose LCD Display to liquids as this may cause damage.

Sanitizing and Decontamination of Interior

• The best decontamination method is a mixture of 30% chlorine bleach with 70% water solution.
• Other methods such as any household detergent, mild soap solution, bleach, hydrogen peroxide, and denature alcohol can be safely used.
• Do not use any petroleum based cleaning solution.
• To perform this sanitizing procedure, cover all inner surfaces with solution, let stand for 30 minutes, and remove.
• Spraying the solution into the inner vessel is preferred.
• Rinse the decontaminated surfaces with clean water and ensure all cleaner residue has been removed
• Allow the tank to dry completely before putting back into service.
