EDGE - Heavy-Duty Cleaner

Description

EDGE heavy-duty cleaner is a multi-purpose cleaner specifically formulated to meet the marine industry’s requirements for cleaning action, safety and environmental considerations. This product combines heavy-duty cleaning ingredients with fastpenetrating wetting agents for the power needed to remove stubborn soils, while remaining mild enough not to harm most surfaces. EDGE heavy-duty cleaner provides an excellent alternative to traditional solvent-based and highly alkaline cleaners.

EDGE heavy-duty cleaner is excellent for cargo tank cleaning of animal and vegetable oils, fats and white mineral oils, and it is suitable for hydrocarbon-free cleaning. EDGE heavy-duty cleaner is a versatile cleaner, especially well suited for machine cleaning and for use in high-pressure spray guns. It is an excellent cleaner for general deck, engine room and steward uses, such as cleaning bulkheads, tank tops, bilges, machinery, engines, tools, hotel services, galley, etc. EDGE heavy-duty cleaner has been evaluated by the IMO Bulk Liquids and Gases (BLG) Working Group on the Evaluation of Safety and Pollution Hazards of Chemicals (ESPH) and found to meet the requirements of Paragraph 1.8.2 of the Procedures & Arrangements Standards and is listed on the IMO MEPC.2/CIRC.11. Only cleaners listed on the IMO MEPC.2/CIRC.11 can be used and disposed of at sea for cargo tank cleaning when cargo residue slops are disposable at sea.

Tank Cleaning

The following tank cleaning instructions are not intended to interfere with the judgment of the Master, Chief Mate, or Chief Engineer in the operation and/or navigation of the vessel. They are meant only as a guide since circumstances for each tank cleaning operation will vary. The recommendations provided are designed to achieve the optimum results and are based on over 40 years of tank cleaning experience.

Application and Use

For cargo tank washing using a mechanical recirculation method, EDGE heavy-duty cleaner should be injected and used at a rate of 2-8 liters per ton of water. EDGE heavy-duty cleaner can also be used for manual spray and direct injection tank cleaning methods. It is suitable for use when hydrocarbon-free cleaning is required. When diluted, EDGE heavy-duty cleaner is suitable for zinc silicate-coated tanks (<10% solution). For general degreasing and cleaning, apply EDGE heavy-duty cleaner with a 2-10% concentration in water (from 1 to 10-50 parts water) to the surface to be cleaned by brushing or swabbing. Allow cleaner to penetrate and lift the product for approximately five minutes, then rinse with water to provide a clean, film-free surface. When mechanically cleaning with highpressure spray equipment, apply EDGE heavy-duty cleaner with a 0.5% concentration in water (1 part EDGE cleaner to 200 parts water). For bilge cleaning and cleaning of other contaminated areas, EDGE® heavy-duty cleaner should be dosed at a rate of 1 liter per ton of bilge capacity or water used. EDGE heavy-duty cleaner meets Alyeska Pipeline Service Company requirements, as evaluated by U.S. EPA Test Methods, as a cleaning agent used to clean tank vessels that discharge ballast water and bilge water to the Ballast Water Treatment Facility in Valdez, Alaska, and which may be used to clean cargo or fuel tanks and bilges of tankers in the Alaska North Slope crude oil trade.
