First, do not use a hard brush to force cleaning, because not all the hardness of aluminum sheet materials are qualified.

Second, do not use detergents with strong alkalinity and strong acidity to clean the aluminium sheet, because not all aluminium sheet materials are qualified for acid and alkalinity resistance.

So, what's the best way to clean up the pattern aluminium sheet?

It is to clean the surface of pattern aluminium plate with plenty of clean water first, then gently wipe the surface of pattern aluminium plate with soft cloth dipped in diluted neutral detergent. After cleaning, it is necessary to clean pattern aluminium plate again with plenty of clean water until the neutral detergent on it is completely cleaned. In particular, we should pay attention to the point that we must not use hot water over 40 degrees!
