A:Answer Hi Rororoyourboat- Thanks for considering our GE Microwave JES1145SHSS! The white epoxy interior is quite durable and holds up well. If properly maintained, you should not expect rust/chipping. To keep your microwave looking like new, we suggest to view the following link for tips on cleaning the interior: http://products.geappliances.com/appliance/gea-support-search-content?contentId=17377 - Also, while there will generally not be a puddle, it is normal to have moisture on the floor or walls of the microwave cavity while cooking, especially if you are microwaving liquids or foods with a high water content (ex. Potatoes). The moisture will dissipate on its own; however, you can also wipe off the moisture with a clean, dry cloth. Keep in touch. We love hearing from you! SUE@GEA
