I always use bleach have with no issue.
Give socks a hose down to remove most debris, Chuck them in a bucket of water with bleach. Leave overnight and then empty out and rinse and leave in clean water to soak overnight again then straight in.
Never worried about using prime or testing for chlorine as is so little residual water can't imagine being any issues, and chlorine dissipates when water is left to stand anyways doesn't it
