The new mineral will be called icecreamite. It consists of ancient deposits of frozen layers of ice cream inside the machine that makes it. It can be cleaned with a screwdriver and a pressure washer. Afterwards, everything around has a pleasant creamy scent. It lingers.
Worse than ice cream is the dust and grime that settles on ceiling exhaust grilles. Cleaning products barely touch it. Two hours of work, a rag torn to shreds, two cans of cleaner, and everything is still wet.
