I'm curious if anybody else gets a funny aftertaste when they make soda water in their whipping siphon? Mine's got a sour-milk-like taste, which would make sense as I made burrata as my first recipe in it, but I've washed it in the dishwasher twice. I've also heard of people getting funny after tastes when using certain cartridges, but I've bought a couple boxes of different types and the taste is the same. Maybe I need to do a deeper cleaning?
