The Nesquik wash will be a spectacular sight. Speaking from experience, and if your machine is a top loader - do not fill machine with water more than half way up the tub. One of my boys did a chocolate nesquik wash with a full tub and it spilled all over the laundry floor. Yes I made him clean it up. Even behind the machine.

Dunno about front loaders. And strawberry nesquik is easily identifiable as such, unlike chocolate. Sympathies for your situation.
