10. aluminum composite panel acp sheet Cleaning method
(1) Removal of light surface soiling
Prior to applying a cleaner, we recommend a forceful water rinse cleaning from top to bottom, low water volume with moderate pressure is better than considerable water volume with little pressure. Simultaneous physical rubbing is also effective. Use a soft sponge or soft rags fully soaked in water.
a. Apply a water rinse with moderate pressure to dislodge the soiling. If this does not remove the soiling, test a simultaneous water rinse with a sponge. If the soiling is still adhering after dry, test a diluted mild detergent.
b. When you use a diluted mild detergent, use it with soft sponges or rags. Wash the surface with uniform pressure and clean the surface in a horizontal motion first and then in a vertical motion.
c. Minimize the drip and splash of the mild detergent and rinse the rundown immediately to avoid streaking. Clean the surface from top to bottom and follow with a thorough rinse with clean water.
(2) Cleaning of medium to heavy surface soiling
In order to remove medium to heavy soiling caused by grease and sealing material, some type of alcohol such as IPA (Isopropyl Alcohol), ethanol or N-hexane is used. Dilute these alcohols by 50% with water; strong solvents-containing cleaners may have a detrimental effect on the coating surface. Do a spot test on a small unseen area. Wash the residues with soap and rinse with water.
(3) Caution
a. Strong solvents and strong cleaner may cause damage to the coating, do a spot test on a small unseen area.
b. Avoid abrasive cleaner. Do not use household cleaners containing abrasives.
c. Do not rub excessively as it may change the coating appearance.
d. Avoid drips and splashed. Remove the rundown as soon as possible.
e. Avoid extremely high and low temperatures. Extremely high temperatures will accelerate the chemical reaction evaporate water from the solution and cause streaking. Extremely low temperatures will result in a poor cleaning effect. Perform cleaning work on a shaded side of the building under moderate temperatures.
f. Do not use paint removers, strong alkali or acid cleaners. Do not use strong organic solvents such as MEK (methyl Ethyl Ketone), MIBK (Methyl Isobutyl Ketone). Treclene (Tri-chloroethylene) or thinner.
g. Make sure that cleaning sponges and rags are grit free.
h. Do not mix cleaner.
(4) Practical cleaning method
Cleaners and detergents are normally local products. A cleaner or a detergent widely available in a one country may not be available in another country. We attached an example of a practical cleaning method in" Appendix 10: Example of practical cleaning method" in section 4. To confirm the harmlessness of your cleaner, contact local distributors or our office. We will perform a test with your cleaner sample.
