Give her a bath, have the room pretty humid (I turn on our shower while she’s in kiddy tub on the sink counter), it comes right off
Tummy time does it for my kiddo. She gets just fussy/s snotty enough those suckers come out on their own as she’s turning her head against the thing she’s lying on lol.
I usually put a chamomile bag in about an inch of Boiled water and wait for it to cool off. I use it as saline water, it also helps take swolleness away
