DIRECTIONS FOR USE/ APPLICATION RATES AND DOSAGE RATES
Pre-wash
Before cleaning with TANK CLEANER EXTRA, it is recommended to prewash tanks with hot water of approximately 50°C except for crude oil, drying and semi-drying oils where a prewash with cold water should be applied.
Direct Injection Method for Cargo Tanks
Undiluted TANK CLEANER EXTRA should be injected at a predetermined rate into the pressure side of the automatic tank cleaning system line on deck by means of an air-operated drum (barrel) pump. Usually an injection rate of 0.1 to 0.3 liter TANK CLEANER EXTRA per 100 liters of tank wash water is sufficient. Cleaning time 2-6 hours. Subsequently rinse with water.
Hand Spraying Method
Spray undiluted TANK CLEANER EXTRA on to bulkheads, frames, stringers, longitudinals etc. using an air-operated drum pump connected with a delivery hose and hand spray gun. After a predetermined reactiontime, tanks should be rinsed with water using the automatic tank washing machines. For spot cleaning only,use hand held hose for rinsing, for instance a firehose with nozzle. Hand Spraying Method is the mosteconomical system in terms of chemical consumption but requires tanks beeing gasfree enabling men toenter tanks. However, Hand Spraying Method has a practical time limitation depending on tank sizes, i.e.total tank surface to be sprayed.
TANK CLEANER EXTRA can also be used for local cleaning and degreasing in engine rooms and on deck. It can be applied by brush, hand spray, immersion soaking or any other conventional means. Apply undiluted onto soiled surfaces and allow a contact time of 15-30 minutes before rinsing off with water.
Recirculation Method
The required solution strength is 0,2- 0,5 % TANK CLEANER EXTRA for cleaning base oil, lube oil and mineral oils. It is recommended to prepare 1,0- 3,0 % TANK CLEANER EXTRA solution for cleaning fuel oil. Recircule the solution at 60-80°C.
After recirculation , rinse tank with water.
