Hairbrushes and combs made of plastic can take a spin, but not wood or natural boar-bristle brushes. Be sure to remove all the hair first to protect the drain.

Fan grilles, switch plates, and vent covers are in if they’re plastic, aluminum, or steel. Enameled, painted, or plated should stay out.

Shin guards, knee pads, and mouth guards―toss them all into the top rack.
