Directions for use

Recirculation:

Recommended to start with 2% solution
Heat the solution to at least 60°C
Wash tanks by recirculation for 60 minutes, or 2 full cleaning cycles.
Strip tank completely
Rinse with seawater after cleaning to remove the detergent and check that the PH is neutral and no foaming in the washing water sample.
Perform final rinse with freshwater or De-ionoised water.
For chloride-free cleaning and passing chloride test, use chloride-free Deionized Water for the final rinse.

General rule of thumb is to have for every 500 m3 tank volume at least 1 m3 of cleaning solution containing 2~3% of Navaclean 823 cleaning solution.
