Hi everyone, might be a stupid question but I'm very over the top with making sure everything's perfect. I washed and sterilized my pumps 2 days ago and never ended up using them. I want to use them today do I need to give them another scrub in the sink then sterilize or can I just throw them as is into the sterilizer? They seem to have water stains so unsure of whether to wash them again or not, even tho they were unused since last sterilize.
