is White King straight bleach?Get some straight bleach and put it in a plastic container. Put the plants in the bleach for 1 minute, then remove them and wash them under tap water. After that, put them in a bucket of tap water and add a triple dose of dechlorinator. Swirl it around and leave for a little while, then rinse them again.
Use bleach that is cold because warm and hot bleach dissolves things quicker.
