Maintenance cleaning: this pertains to regular cleaning in the sense of removing dirt, contaminants and residuals from normal usage. The routine cleaning will be somewhat different depending on the stainless requirements at stake as illustrated by the following examples:
aesthetics in interior&exterior decoration: removal of dirt, particles outside, fingerprints and oily marks.
food processing, whether industrial or household: the requirements are essentially mandated by hygiene considerations & regulations. Dirts, fats, food fragments, particularly salt-containing, are the target of cleaning. In all the situations of maintenance cleaning, the process should start with warm water, with then use of ammonia or mild alkali detergents. Grease, fats, oily marks will be best dealt with organic solvents and alkaline cleaning products. Follow by proper rinsing and drying.
