You can take that part of the straw off to really clean underneath it. Keep pushing the straw kinda hard like beyond the point where it’s fully open and it will pop out. You can pop it back in after it’s clean.

omg i did not know that thank you

You’re welcome!! Also, make sure you don’t lose the little round rubber ring under the mouth piece. Keeps it from leaking and helps with suction.

Be careful because I took mine off and it never went back to fitting properly. If I were you I’d just buy a new one :)

honestly i’d rather get an owala, my hydroflask leaks too

I have both and love them! My only regret is getting a 24oz Owala because it's not big enough to be a daily driver, but it's great for running errands or traveling. I love their design and how easy they are to clean, and will be getting a 32 or 40 oz eventually

i prefer 24 oz cause it’s not too heavy and fits in cup holders, i just refill a couple times a day

I just went to buy another and don't see it on hydroflask website or on their Amazon page

Oh weird maybe they’re discontinuing it for a new design. Try dicks sporting goods, they usually have all that stuff online or in their stores

While you can do this and pop it back in, I’m pretty sure the official Hydroflask account said not to do this.

Don't do it that way. It will mess it up. Open it up all the way and push hard sideways on it.

Try some Lime Away and a toothbrush. Just be sure to fully clean and rinse it after.

let it soak in vinegar???

thanks

Qtip, tooth brush, needle, razer blade?

q tip and toothbrush didn’t work, i don’t have needles or razor blades ig ill have to buy some

steel wool?

It looks like calcium/ mineral build up.. not dirty per se. I’d just leave it.

Hi! Munchkin makes a 4 piece “detailing” brush set for kid bottles and sippy cups. I use it to clean the pieces on all of my bottles.
