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 handwash silicone straws because I know no amount of automatic dishwashing will clean it.
They specifically make very special pipe cleaner-like cleaning instruments for these things. Often, the bottle may even come with it. Very handy
Edit: this is the one I have
Although I only ever drink water out of it, I do make sure to wash up the straw at least once a week.
Thing is, that the straw plugs into a gasket on the bottom of the lid and is at least partly silicon all the way through to the spout. I make sure to run the cleaner brush thing through that very regularly as well. Sometimes several times a week just to make sure it’s always clean.
My wife was using her tumbler for just plain water. She would rinse and reuse each day. She got a stomach bug and I was getting her water and noticed the mold on the threads of the screw top. It was so hard to see since the lid was black too.
Even if it’s just used for water, clean them thoroughly and regularly.
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.
Who relies on a dishwasher to clean inside a BOTTLE? Get a bottle brush and wash it by hand, it takes 60 seconds
I just want to know if it’s just “not safe” or straight up dangerous. Why don’t they tell us that?
glass straws ftw. best mouthfeel (lol) of any straw AND you can see if there’s dirt in em
Seems you should also know that dishwashers only work so well as the detergent and water can access the objects inside. They are not a magic device that clean everything without fail.
They should.come with someone to wash them for me
