DIRECTIONS FOR USE/APPLICATIONS & DOSAGE RATES : Before cleaning with Careclean Buffer it is recommended to prewash with hot water.
Never dilute BUFFERCLEAN with seawater of river water. For solutions always use freshwater.

HAND SPRAYING METHOD
1. Apply 1 litre undiluted BUFFERCLEAN per 10 Ltr of Water
2. Let the cleaner penetrate for 30-45 minutes
3. Wash down with freshwater and check results preferably with a wall wash test kit.

NOTE: Heat is achieved by the use of a heat exchanger, steam coils or live steam injection. The advantages of this method are that heat and chemicals are recovered and can be used again to clean additional tanks. It is important to use fresh water only. The use of river- or seawater will cause a reaction which decreases the efficiency of the solution for tank cleaning. 

Dosage

Recirculation Method – Highly Effective & Recommended Tank Cleaning Technique:
1. Make a 10% solution in freshwater in a slop (solution) tank.
2. Heat the solution to a maximum of 60.C.
3. Wash tanks by recirculation for 60 minutes.
4. Usually one solution is used for washing 3-6 tanks
5. Rinse with freshwater and check the results
6. For chloride-free cleaning and passing chloride test use chloride-free De-Ionised Water for the final rinse.

Recirculation Method Recirculation is . In this method a chemical solution is pumped via a closed loop through a mechanical tank washing machine.
 

The Recirculation Method is a highly effective and industry-recommended technique for cleaning tanks, pipelines, and other enclosed systems. This method involves continuously pumping the cleaning solution—such as a neutral pH or alkaline tank cleaner—through the system in a closed loop, ensuring thorough removal of contaminants, residues, oils, and deposits from all internal surfaces.

Recirculation ensures maximum contact time, uniform distribution, and minimal chemical wastage, making it ideal for cleaning chemical storage tanks, marine tanks, heat exchangers, and process vessels.

Key Benefits of the Recirculation Method:

• Efficient & Uniform Cleaning of all internal surfaces

• Reduces manual cleaning effort and downtime

• Minimizes chemical consumption through reuse in the loop

• Maintains controlled temperature and concentration for optimal performance

• Suitable for large tanks, complex pipework, and hard-to-reach areas

Recommended for Use With:

• Neutral pH Tank Cleaners for sensitive coatings

• Alkaline/solvent-based degreasers for heavy-duty cleaning

• Ideal for food-grade, pharmaceutical, chemical, and marine applications

Notes

Buffer Cleaner will in a cost effective way remove lead, hydrocarbons, chloride, sulphides etc. from the pores of zinc silicate and epoxy coatings. It has been designed with a pH value of 5.5 for safe application on these types of cargo tank coatings.

Precautions

The ordinary cleaning method with a synthetic soap takes a long time and is insufficient in removing the described contaminants. A week acid solution in combination with synthetic soap gives a much better cleaning result.

BUFFER CLEAN is used as a final cleaning procedure when the cargo tanks have to be completely free of lead, chlorides, sulphides or MTBE prior to loading of special high purity cargoes.
