I've got some Grovia AIOs, about 24 prefolds and a few PUL covers...
I know the AIOs and prefolds will need a bunch of washes to prep...Can I prep them together? Will colours run? What is the best method? A little bit of detergent and hot/warm/cold water? Do I need a bunch of rinses each time? Do I use detergent each time?
But the PUL covers, I just wash once and dry once, right? Again... will colours run? Hot/warm/cold water?
I boiled the prefolds for about a half hour this afternoon to get them started.
Re: Prepping my stash...
1. Grovia AIO's seem to be all cotton besides the outside - so should be find prepping with the prefolds. You will need hot water and little detergent for the first run through. Then dry. Then wash in hot and dry. Repeat about 5 or 6 times. You could also boil the prefolds for 20 minutes and then dry, wash and dry and they should be good. I wouldn't do that to the Grovias because of the outer and snaps. And now that I read your last line - you only need to wash and dry your prefolds one more time.
2. PUL covers hot wash and hot dry. I've never had colors run.
