How to clean the arrays? 

The array is needed to be cleaned after every use by soaking in a combination of 30 parts water and 1 part of phosphoric acid or household bleach or white vinegar. Soak about 30 minutes, rinse it off with water and blow dry it or let it air, then seal it in a plastic bag.
