Order an ultrasonic. But actually. ~ 15-20min/ rack.
Otherwise magic eraser the rolling edges, dawn + toothbrush on the faces, and toothpicks in the canes and rings. Probably about 1-1.5hr/ rack, take your pick.
Ultrasonics are great at getting off crud but I honestly feel like dish soap and a washcloth or scrub brush are better at removing regular old dirt and smoke etc stains/smell
I use A spoonful of lundmark TSP in a foot washing bucket with warm water. I do a barrel at a time with light scrubbing from a toothbrush. Hooker juice melts off. No elbow grease required. About 5 seconds per chip. Wear gloves and have a separate bucket for rinsing.
Definitely recommend TSP, also recommend rinsing and soaking in some warm (dish) soap water and scrubbing with a gentle bristle nail brush and/or magic eraser and soapy water. Should come clean pretty easily
