Dharma says to agitate the bath.
Last summer I tied and bleached a shirt but didn't untie it when rinsing and bathing in anticlor. I then dyed and batched it and in the final washout, the shirt developed holes in the tied design. It is hanging on a wall in my workroom to remind me to untie after bleaching - the holely shirt.
