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

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.
You're viewing a single thread.
From my experience, most canteens they sell are marked as not dishwasher safe.
"Not Dishwasher Safe" == "We didn't want to spend the money testing it and want to free ourselves from liability"
Sometimes it's true, sometimes not
A couple of things come to mind here:
I own a metal one which I assume was dishwasher safe but somehow water got trapped inside the 'extra' parts of it which could be unsanitary due to the water eventually stagnating.
Another is that the heat from the dishwasher can warp and silicone or plastic parts which will render them unusable eventually.
Not saying you're wrong but this is what I consider from the warning they provide.
General purpose silicones like silicone sealants and gaskets tend to have a high-temperature limit of around 200 C to 250 C and also lower temperatures of -50 C to -75 C.
So your dishwasher isn't going to warp silicone, but lots of plastics, yeah.
I've seen a lot of fabrics that say "Dry Clean Only" because the manufacturer was too lazy, but my experience with dishes finds that the labels are generally quite accurate. Putting a non-dishwasher-safe item in usually ruins it.
Well yeah “Dishwasher safe” is an endorsement. The lack of an endorsement is not an endorsement to the contrary. Something is only “dishwasher unsafe” if it says “Hand wash only”
Who relies on a dishwasher to clean inside a BOTTLE? Get a bottle brush and wash it by hand, it takes 60 seconds
Eh, if the bottle is just for water there's enough spray and heat to kill and rinse it usually.
I just want to know if it's just "not safe" or straight up dangerous. Why don't they tell us that?
How would they know what sort o bacteria you cultivate in your abode?
Usually things marked not for dishwashers can’t hold up to the abrasive nature of the detergent or the heat of the water over a prolonged wash cycle.
Dishwashers are not magical devices, they basically just spray sandy soap-water for a long time.
