Starting with a newly cleaned, reusable container, until you disassemble and scrub all the parts with soap.
I can go a few months. I drink one big one a day and leave the cap off overnight until I refill it in the morning. Leaving the cap off really helps keep the mold away
I clean mine whenever I start to see a visible crust/film form around the spout I drink from. It’s just for water, so that’s pretty much the only part that gets nasty.
Honestly I think its been years. There’s some hard water on the lid, but no traces of mold or anything like that. It also tastes and smells normal to me.
I only get dishwasher safe coffee tumblers and I wash them daily. I have enough respiratory goo without adding mold to the mix.
Wash them???
6+ months 🫠
I usually clean it once I can no longer ignore the pink scum and black mold growing in it 🙊
…… yup - came here to say “when I notice the black stuff”.
I appreciate your honesty, and I’m not far behind. I’ll scratch off build up sometimes and easily go months. Washing it is probably a similar frequency to getting my haircut.
If we’re talking for water drinking only? Rinse out each day. Wash every other day. If I put coffee in, full wash each day.
Mold and bacteria can grow in it within a day or two, even if it’s not visible. I hand wash mine once every week or two. I also sanitize it regularly by pouring boiling water in the tumbler (it’s metal) when I make tea, then leaving the hot water in for about 10 minutes.
What if I’m very regularly using it for tea?
that’s probably bad, huh? <starts nervously chewing fingernails>
I wash the parts my mouth touches pretty regularly. The other bits, especially if the don’t get backwash? Maybe a few times a year the whole thing goes in the dishwasher. Disassembly and careful hand washing? Bitch, you’re a water bottle. You don’t get that!
I don’t deep clean mine unless its needed
I usually just rinse it out and call it a day.
About 16 years and counting
Typically I rinse it out daily and bout 1/week actually scrub it with soap or put it in the dishwasher
Every couple of days I will squirt some dish soap in there with water and give it a thorough shake. Every week or so I actually disassemble it for a proper clean.
Asking because the tumbler I use has a lot of little parts, so I easily go weeks between washing. I’m hoping someone more knowledgeable than me shares a good reason why I shouldn’t do that, because I feel a bit self conscious about it, but not enough to frequently wash.
It’s fine until it’s not, but you can do a lot to combat growth by rinsing it with vinegar and boiling water, then letting it fully dry before using it again once or twice a week
Not too long. Like once a week or every other week. What happens is I forget and leave water in it, and then I’ll wash it.
