So to clean it off, I tried just a piece of tissue and it was REALLY tough to get off. It was only a bit easier with cleaner, a wipe, and a lot of arm grease. But it required a LOT of arm grease.
So I got to thinking and grabbed my sponge with the rough side from the kitchen. It came off super easy using the rough side of the sponge! Awesome stuff! Cheap, easy, and accessible.
