Directions for use

Pre-cleaning of Tanks

  • Before cleaning with NAVACLEAN 848 – NEUTRAL CLEANING CONCENTRATE it is recommended, for non-drying oils, to pre-wash the tanks with hot water at 50°C. For drying oils and semi-drying oils the pre-cleaning should be made with ambient water and it should be carried out immediately after completion of discharge of the cargo in order to retard the oxidation and hardening of oil residues.

Recirculation Method

  • NAVACLEAN 848 – NEUTRAL CLEANING CONCENTRATE should be recirculated as a 0.5% solution for a period of 2-6 hours. The water temperature should be approx. 35-60°C. After chemical cleaning the tanks should be rinsed thoroughly with sea water, fresh water or di-water depending on availability and requirement.

** The maximum concentration is 10% and a maximum temperature of 60°C
