laundry, wash, pour on, rinse
濯 centers on using water to clean or rinse something, especially laundry. The idea of pouring water on something to wash it connects all the given meanings.
濯 combines 氵 (water) with 翟, which likely contributes the sound and may relate to cleaning or washing. The exact historical development of 翟 in this context is uncertain.
Water 氵 pours over the right side 翟 like rinsing clothes in a stream. Picture a laundry scene where water flows over the fabric to wash it clean.
For タク, imagine washing a tacky shirt: tack -> タク, and the water rinses away the stickiness.
