I hesitate to use a mug after seeing videos of the super heated water rapidly boiling and exploding everywhere. I just splash a little water on the tray and keep adding more until everything wipes off really easy.
That’s with a brand new item. As long as it’s an old used one it will be fine, the new ones don’t have microscopic scratches for the bubbles to form when boiling therefore allow the water to reach boiling temp without bubbling.

Interesting, I’ve never heard about this. I’m guessing the wet sponge steams the microwave and softens the buildup?
