Gobel 4" x 3/4" Fluted Non-Stick Tart / Quiche Pan with Removable Bottom

How can I best maintain the non-stick qualities of this item?

To prevent food from sticking to your non-stick surface, we recommend lightly coating it with oil, wiping off any excess with a soft cloth or napkin. Using sprays on non-stick coatings can actually cause food to stick more readily than using a fat or oil. Sprays can leave a glue-like coating, often missed during the cleaning process, which will begin to build up and cause foods to stick. Additionally, metal utensils and abrasive cleaners should not be used with non-stick surfaces to prevent scratching and damaging the coated surface.
