Etymology
垢 combines 土 (earth/soil) with 后, which likely contributes the sound. The idea is dirt or filth associated with the ground.
Meaning mnemonic
The left side is 土 (earth/soil), and the right side 后 looks like a container. Picture soil and grime collecting inside a container, forming stubborn dirt.
Reading mnemonic
For コウ, imagine scrubbing away dirt with a coarse cloth: coarse -> コウ, and the grime comes off.
