Washing??

[~clover~]

I wouldn't use bi-carb. Don't use vinegar or bleaches. PUL - the water proof layer will loose its water proofness.
Hemp should be hot washed & dried 3 times before use, bamboo once. They will hold more after 10 washes.
PUL shouldn't get too hot either. Water under 60 deg & dryer on warm if needed
I try to use grey water friendly powder. It has less chemicals on bub's skin.

BTW - after the intial washes, cold water is ok. The odd hot wash/strip wash is good. About once a month I do mine.
