Directions for use

Recirculation:

Recommended to start with 2% solution
Heat the solution to at least 60°C
Strip tank completely
Wash tanks by recirculation for 60 minutes, or 2 full cleaning cycles.
Final rinse with freshwater after cleaning to remove any salt deposits and check the results
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.
