Aluminum profile surface have dustdeposition and the anodizing film absorbs the moisture. These will lead 

thecorrosion of the anodizing film, especially there is sulfide in the air. So weneed to clean 

up the surface of the aluminum profile to extend the servicelife.

The periodic cleaning cycle is generallysix months. The interval can depend on the degree of environment 

pollution.

The method of cleaning can depend on thedegree and scale of the possible destruction on anodizing film. For 

smallpieces of profile, we usually wipe gently by hand. For large pieces of profile,it is required to try to dissolve 

the viscous sediments. We usually clean thedirty with hot water containing a suitable lubricant or neutral soap 

solution.We also can use a fiber brush to remove the attached dust.

It’s not allowed to use the sandpaper, wirebrush or other friction material. It’s also not allowed to clean with acid 

or alkali.These will damage the anodizing film. After the cleaning, we need to wash it inwater. Especially in the 

cracks and dirt, we need to use a soft cloth withalcohol to scrub them. Finally, we can use a high-quality wax to 

do the polishingtreatment to the surface.
