YSK: many water bottles come with silicone gaskets that must be removed and washed to prevent mold and mildew buildup. - eviltoast

Dishwashers won’t clean these gaskets if they’re washed while installed. Oh, and those silicone straws can come out of the dishwasher nasty too.

    I sanitize my water bottles in the sun. After washing them I put them on a south-facing windowsill and let the UV light kill every last living microbe that might be lurking in the crannies. (it’s always the crannies that get you, the nooks are usually fine)
