Things You'll Need
Stainless Steel and Aluminum Cleaner or equivalent
If your aluminum trays seem discolored from wear or you have heat stains, cleaning them is the only solution. Aluminum trays are often used for a party or other social gathering. They get dirty and dingy rather quickly. After the party, you may not feel like washing all the cookware or serving trays and then they sit at least overnight while leftovers become hardened. Cleaning aluminum trays does not have to be an expensive or time-consuming venture.
Soak your aluminum trays in boiling hot water. Let the trays immerse for about 30 minutes.
