A very good reminder to separate all parts, clean and sterilize them. i keep one of those containers you can put baby bottle parts in to run through the dishwasher with our various lids and lid parts.i know I go a bit of overkill here but a few times a year I add a bleach to hot water mix for a few hours soak for tea cups and coffee mugs before washing them by hand and running through the dishwasher. I love that our old tea cups and coffee mugs look new again.
