Aluminum sheet care and maintenance
The concrete steps of aluminum cleaning are as follows:
1. Rinse the plate surface with plenty of water;
2, moistened with water by wiping the plate surface detergent diluted soft cloth lightly;
3, Rinse the board with a lot of water, this step will wash away dirt;
4. Check the board, and clean the dirty place with detergent;
5, Rinse the board until all the detergent is washed away.
Note: Do not wash the hot plate surface (when the temperature exceeds 40 ° C), because of excessive evaporation of water on the plate surface paint harmful!
Of particular note is that, please use suitable detergent, a basic principle is: Be sure to use a neutral detergent! Do not use strong alkaline detergent such as potassium hydroxide, sodium hydroxide or sodium carbonate, strongly acidic detergents, abrasive detergents and the detergent soluble paint.
