Cleaning & Sanitation

How to clean your tank before first use, between chemicals and on a regular schedule, without damaging it.

Before first use

Rinse out dust and packing debris with clean water.
Do the water test from Installation Info at the same time.
Drain fully before adding chemical.

Changing chemicals

Empty the tank and rinse or neutralize the old chemical as its Safety Data Sheet directs.
Check the new chemical against our compatibility chart for the tank and the gaskets.
Never let residues of two chemicals that react with each other meet in the tank.

Water or food-grade use

The plastic the tank is molded from is food grade.
Clean the tank with a cleaner or disinfectant that is compatible with the tank resin, following the product's label directions.
Rinse thoroughly with clean water before use.

What not to clean with

No caustic cleaners in PVDF tanks. PVDF is rated Not Recommended for sodium hydroxide (caustic soda), so don't use caustic cleaning solutions in a PVDF tank.
No wire brushes or abrasive pads. Use soft brushes and low-pressure spray so the surface isn't scratched.
Don't exceed the tank's rated temperature with hot water, steam or warm cleaning solutions.

Clean from outside when you can

Spray down the inside through the manway with a wand rather than climbing in. A tank is a permit-required confined space under OSHA 29 CFR 1910.146: anyone who enters needs a permit, air testing, an attendant and a rescue plan. Lock out pumps, mixers and heaters first.

Dispose of rinse water and residue as the chemical's Safety Data Sheet and local rules require.
