Marine Clean SC

Dose:
 

• Prior to use of any chemicals, make sure the tanks and lines are well stripped and drained.
• A proper pre-cleaning will reduce the amount of chemicals required.
• Further, do not overheat as this may change the characteristic of the cargo and in some cases burn the cargo to the bulkhead.
• Carefully read the cargo specification.For vegetable, animals, and fats: Tanks containing drying or semi-drying oils should be flushed or pre-washed or moisten as soon as possible after completion of discharging to prevent formation of hard tenacious residues.
• The temperature used for precleaning will depend on whether the cargo is drying, semi-drying or non-drying, and the cargoes melting point. Thus an individual cleaning operation should be made for each cargo.

 Due to the fact that the zinc is porous, a prolonged precleaning with lower temperatures is highly advisable prior to introduction of chemicals on such linings.

•  Flush tanks with ambient seawater to remove remaining cargo to slop. (As per MARPOL 78/73).
•  Recycle tanks with increasing temperature for 2-8 hr, depending cargo and size of tank. This is a very important operation, as it will remove oilymud and residues in the coating/steel.
•  Make a mixture with fresh water and 0,5 -2 % Marine clean SC. Insert the mixture into the tank and commence the re-circulation wash for 2-8 hr. Increased temperatures will improve the cleaning result. Maximum effect from chemical at 650C. Do not overheat,   as this may burn the cargo.
•  Flush tanks with large amount of warm seawater (2-3 hr) to remove any residues of Chemicals.
•  Flush tanks with freshwater to remove salts,mop and dry.

Spot cleaning after most CPP / hydroc- hydrocarbons.
 

• Marine clean SC may be sprayed on the bulkhead neat or diluted , to areas where residues remain after tank washing,“Spot    Cleaning”. A heated dilution is found to be very efficient.
    
• Product should be allowed to stand for 10-30 minutes prior to re-washing areas. Do not leave the product to dry on bare coating.
   
•  Clean areas by flushing manually with high pressure, using fresh water, or by performing a re-circulation. For     persistent deposits, agitation by scrubbing will assist the cleaning operation. Heated water will increase the    cleaning effect .
