Care guide

How to clean a COLDEST bottle

We recommend hand washing every COLDEST bottle in warm soapy water: printed, glitter, glow and glossy designs are not dishwasher safe, and hand washing protects the finish and the insulation. Rinse it daily and wash the bottle, lid and straw with warm soapy water after anything other than water. To deep-clean a lid, soak it for 30 minutes in warm water with a little dish soap or vinegar, scrub the spout, threads and gasket, rinse, and air-dry it open. Never freeze or microwave the bottle.

How to clean it

Clean a COLDEST bottle in five steps

A daily rinse, a wash after anything but water, and a deep clean for the lid when it needs one.

  1. Rinse it daily

    A quick rinse every day keeps it fresh between washes.

  2. Wash after anything but water

    After coffee, tea, juice or a shake, wash the bottle, lid and straw with warm soapy water. The 3-in-1 brush is long enough to reach the bottom of tall bottles.

  3. Deep-clean the lid

    Soak the lid for 30 minutes in warm water with a little dish soap or vinegar. Scrub the spout, threads and gasket with the small brush, and run the thin brush through the straw.

  4. Air-dry it open

    Rinse, then let the lid and bottle air-dry open, or on a rack, so nothing stays wet inside.

  5. Check the seal

    Before you screw the lid back on, make sure the silicone seal sits flat inside it and the threads are clean.

Why hand wash

What hand washing protects

Dishwashers run at varied temperatures. A sink and a brush are kinder to a COLDEST.

  • The insulation

    We recommend hand washing to protect the insulation that keeps your drink cold, too.

    The seal

    The small brush gets into spouts, threads and gaskets, where buildup hides.

    Being able to see where my brush is going is awesome, AND the fact that I can scrub the crevasse where the seal is... *chefs kiss*

Questions

Cleaning and care questions, answered

Dishwasher and care

Is a COLDEST water bottle dishwasher safe?
We recommend hand washing every COLDEST bottle in warm soapy water. Printed, glitter, glow and glossy designs are not dishwasher safe, and hand washing protects the finish and the insulation.
Why hand wash instead of the dishwasher?
Coldest recommends hand washing all of its products in warm soapy water, due to the varied temperatures of dishwashers. It also keeps printed, glitter, glow and glossy finishes looking new.
Can I freeze or microwave my COLDEST bottle?
No. Never freeze or microwave the bottle.
Can I put hot drinks in it?
Yes, but use care with hot liquids: pressure can build inside, so open the lid slowly, pointed away from you.
How often should I clean my water bottle?
Rinse it daily, and wash the bottle, lid and straw with warm soapy water after anything other than water. Deep-clean the lid when it needs it: a 30-minute soak in warm water with a little dish soap or vinegar, then scrub and air-dry it open.
Does the warranty cover scratches or peeling?
Not dents or scratches: normal wear, drops and misuse aren't covered. If paint peels or the steel rusts without a drop or misuse, start a claim with photos through our return portal. Details: Warranty and Returns.

Tools and accessories

What does the 3-in-1 brush include?
Three tools: a large brush for the inside of the bottle, a smaller brush for lids and tight spots, and a long, thin brush for straws. A loop on the handle lets it hang to dry.
★★★★★

Very helpful to clean the bottles thoroughly since you can’t get your hand into the bottles. Bottle, straw, and lid brushes. The ring helps for hang drying!

JENNYVerified buyer · Sep 2023
Will a brush scratch my bottle?
The COLDEST brush is made for stainless steel water bottles and its bristles are soft. As with any brush, rinse grit out of the bottle first.
How do I wash the boots and the paracord?
Take the boot off the bottle and wash it in the dishwasher. A paracord can stay on the bottle in the dishwasher, but the polyester dries faster if you take it off. Wash the bottle itself by hand.

Lids and straws

How do I deep-clean a lid?
Soak it for 30 minutes in warm water with a little dish soap or vinegar, scrub the spout, threads and gasket with the small brush, rinse, and air-dry it open.
★★★★★

I wanted this one just for the small brush for my lids. … It's so much easier to clean my water bottle lids now

ShannonVerified buyer · Oct 2023
How do I clean a straw lid and its straw?
Rinse the straw after each use and wash it with warm soapy water. The thin straw brush in the Water Bottle Brush gets inside it, and the small brush cleans the spout. A straw that's seen better days is easy to swap: reusable straws come in packs of 5, 10 or 20.
★★★★★

Having extras mean you can continue to use your bottle while the Straw you're cleaning has adequate time to dry properly.

LekitaVerified buyer · Aug 2025
My lid or bottle smells. What should I do?
Give the lid the deep clean: a 30-minute soak in warm water with a little dish soap or vinegar, a scrub of the spout, threads and gasket, and a rinse. Wash the bottle with warm soapy water, then let both air-dry open before you close them up.
★★★★★

this is my tea cup. and it does not hold that tea smell.

ShannaVerified buyer · 20oz Tumbler · Nov 2022
How do I keep mold from building up in the lid?
Wash the lid and straw after anything other than water, and always let them air-dry open, so nothing stays wet inside. When you see buildup, soak the lid for 30 minutes in warm water with a little dish soap or vinegar and scrub the spout, threads and gasket with the small brush. Replace a straw you can't get clean.
How do I clean under the slider on the 20oz Tumbler lid?
Rinse under the slide after coffee or milk drinks. For anything stuck under the slider, soak the lid in soap and water, ideally overnight; the 3-in-1 brush helps too.
My lid leaks after washing. What's wrong?
Check that the silicone seal sits flat inside the lid and the threads are clean, then screw the lid on until it stops, without forcing it. If a leakproof lid still leaks when closed, start a claim through our return portal with a photo or short video.
