Careclean Alkaline

Careclean Alkaline is a potassium hydroxide based alkaline cleaner which is applicable at lower temperatures (20 - 60 °C). Careclean Alkaline is suited to remove vegetable and animal oils and fats, even hardened or carbonized. Besides tank cleaning, Careclean Alkaline is used for general cleaning and maintenance on deck, in the accommodation and in the engine room.

Careclean Alkaline provides economic removal by saponification and emulsification, at low cleaning temperatures (20 - 60 °C), of:

• Vegetable, fish, animal oils and fats
• FAME, palm oils, palm fatty acids
• Other drying and semi drying oils, mineral oils and Inert Gas Soot

Before cleaning with Careclean Alkaline it is recommended to prewash with hot water. For drying or semi-drying oils a prewash with cold water should be carried out immediately after discharge of cargo to prevent against oxidation and hardening of oil residues. After 1 cycle slowly start to increase the water temperature to increase effectiveness of the prewash.

Recirculation is highly effective and widely used. In this method a chemical solution is pumped via a closed loop through a mechanical tank washing machine. The chemical solution is normally prepared in the tank to be cleaned or in the slop tank. Heat is achieved by the use of a heat exchanger, steam coils or live steam injection. The advantages of this method are the recovery of the heat and chemicals to clean additional tanks. Careclean Alkaline is circulated as a 1 - 5 % solution at 20 - 60 °C for a period of 2 - 6 hours. After circulation rinse thoroughly with water. Depending on the degree of contamination one solution can be used to wash 1 - 3 tanks.

Inject 1 - 5 % of Careclean Alkaline directly into the tank washing system. The recommended cleaning temperature is 20 - 60 °C. When completed rinse thoroughly with water.

Depending on the amount and character of the contamination, Careclean Alkaline is to be used pure or diluted at a temperature of 20 - 60 °C. Allow the product to work for 20 to 60 minutes and spray afterwards with a powerful high pressure water jet. Warm water is to be preferred.

For slight oil-contaminations, Careclean Alkaline can be diluted with water to a 10 % solution. Heat the liquid with a heating coil or by means of steam injection to 20 - 60 °C. Submerge the objects to be cleaned in a bath for several hours. Brush the objects while rinsing them or spay with a powerful waterjet. In case of heavily contaminated objects, Careclean Alkaline is applied undiluted in an immersion bath, for example: to remove old paint layers, to clean oil and grease filters, to clean deep fry equipment, to clean baking ovens, etc.

Careclean Alkaline is used to clean cargo holds after carrying cargoes such as pet coke, coal and mineral oil residues. After sweeping and demucking apply Careclean Alkaline in a 10 - 50 % solution depending on the contamination. Let the product soak for 30 minutes making sure not to let the solution dry on the surface. Then spray off with water.

Careclean Alkaline can be applied by the Caretech Hold Cleaning Kit.

For general cleaning on deck use a 1 - 10 % solution and in the accommodation a 1 % solution of Careclean Alkaline in luke warm water. Apply the solution by means of brush or mop. For general cleaning allow soaking for a few minutes before rinsing off with water. In case of hardened or carbonized oil residues soak the contaminated area as long as possible without letting the liquid dry out, brush off with water.

For cleaning of fire caused smoke deposits use a 1 - 10 % solution.

Careclean Alkaline is suitable for use on most metals except for aluminum, tin, zinc and galvanized materials.
