I ran my TNG through the subway. Cleaning with degreaser and rubbing etc is too much work.
If it's off, it takes 10min of a heated cycle without detergent. Clean as new.
Found a ton of cracks in mine once it was cleaned though haha. Had to epoxy the hell out of it. Oh and to clarify i know most of them were there, you just couldn't see them until it was cleaned. Bleh
