Every Yogi has a PureTaste ceramic interior, and ceramic is about the easiest drinking surface there is to keep clean: it's non-porous, so it doesn't hold onto yesterday's coffee, and it rinses clean with warm water and a drop of dish soap. Here's how to look after the whole tumbler so it stays that way for years.

Quick answer: what goes in the dishwasher?

• Evolution (24oz, 30oz, 40oz) — tumbler, Flip & Sip lid, spout, seal and straw are all dishwasher safe on the top rack.
• VoyagerOne (12oz) — tumbler and lid are dishwasher safe on the top rack.
• Elements Coffee Tumbler (16oz) — hand-wash the tumbler to protect its high-gloss finish. The Flip-Lock lid is fine on the top rack.
• Slide & Sip lid and all replacement lids, spouts, seals and straws — top rack.

Top rack matters. The bottom rack sits closest to the heating element, and prolonged high heat is the one thing that can hurt a vacuum-insulated tumbler.

Everyday cleaning

Warm water, mild dish soap and a soft sponge or bottle brush. That's it. Rinse the tumbler, wash the lid parts, and let everything air dry with the lid off. For most people this is a 30-second job at the sink and it's all the tumbler ever needs.

The ceramic interior doesn't need special cleaners. Skip anything abrasive: scouring pads, steel wool and scouring powders can scratch the ceramic just as they'd scratch a ceramic plate.

Cleaning your lid

Lids are where buildup hides, because moisture gets trapped between the silicone seal and the plastic. The fix is to take the lid apart and dry the parts separately.

• Flip & Sip lid (Evolution) — the spout, silicone seal and straw all come out without tools. Step-by-step photos and deep-cleaning tips are here.
• Straws — run a straw brush through after anything other than water, or drop the straw in the dishwasher basket.
• Seals — pull the silicone seal off and wash both sides; it's the part most likely to hold odor if it's put back wet.

Lubricate the ring seal so the lid screws on easily

Every Yogi lid — Evolution, Elements and VoyagerOne — has a wide silicone ring around its underside that seals against the cup as you screw it down. When it's dry it drags on the ceramic rim, which makes the lid feel stiff or stop short of fully tight. The fix is in your kitchen: put a drop of olive oil or vegetable oil on a fingertip and rub a thin film around the ring, then wipe off any excess. The lid will turn on smoothly, seat all the way down, and seal properly — this is also the trick for a lid that's always felt hard to get into position. Reapply whenever the lid feels stiff again, usually after a few washes. Food-grade silicone grease works too and lasts longer if you have it. Skip petroleum jelly; it breaks silicone down over time.

Using the dishwasher

• Top rack for everything, including the tumbler body.
• Use a normal cycle. Skip high-heat, "sanitize" and pots-and-pans settings, and never run a Yogi through a commercial dishwasher. Extreme heat can compromise the vacuum seal and reduce how long your tumbler holds temperature.
• Avoid detergents high in chlorine or bromide for the same reason.
• Colors and artwork last longest with hand-washing, so if you have a printed or special-edition Yogi, the sink is the better choice.

Stains and stubborn odors

• Coffee or tea staining: fill the tumbler with warm water, add two tablespoons of baking soda, and let it sit overnight with the lid off. Rinse in the morning.
• Odor in the lid or seal: soak the lid parts in equal parts white vinegar and warm water for 15–20 minutes, or in warm water with a denture-cleaning tablet. Rinse well and dry the parts separately before reassembling.
• Always soak with the lid off. A sealed tumbler soaking in warm water can build pressure.

Please don't

• Use bleach or chlorine-based cleaners on any part of the tumbler.
• Use abrasive pads, powders or steel wool on the ceramic.
• Put your Yogi in the oven, on a stovetop, or in the microwave. Not even on a double dog dare.
• Put it in the freezer. Liquid expands as it freezes and can damage the vacuum seal.
• Pour boiling water over the lid parts. The Tritan plastic and silicone are made for hot drinks, not for being boiled.

Getting the most cold (and heat) out of your Yogi

For maximum cold: pre-chill by filling with ice and water, let it stand for five minutes with the lid off, then empty it. Fill to the top with ice, add your drink, and keep the lid on. Top up your drink through the day and the ice keeps working. The Evolution is rated for up to 48 hours cold; the Elements and VoyagerOne for up to 24.

For maximum heat: pre-heat by filling with very hot tap water, let it stand for five minutes with the lid off, then empty it. Fill with your hot drink and keep the lid on. The Evolution and Elements are rated for up to 5 hours hot; the VoyagerOne for up to 4.

A word about hot drinks

Heat expands. A hot drink, and the air trapped above it, both take up more room as they warm the tumbler, and under a sealed lid that shows up as pressure — a spout that spits when you flip it open, or a lid that's suddenly hard to unscrew. Two habits prevent it. Don't fill above the bottom of the threads; leave about a quarter inch (6mm) of space. And after you pour something very hot, leave the lid off or the spout open for a couple of minutes so the steam escapes before you seal it. Make sure the lid is fully assembled and tightened before you pick it up, keep a hot Yogi out of reach of children, and take the first sip carefully — hot liquids can scald.

Don't use a closed lid with carbonated or fermenting drinks. Pressure can build up inside a sealed tumbler and force the lid open, which can spill hot or cold contents suddenly. If you want to keep a soda or sparkling water cold, leave the spout open or use the tumbler without the lid.

Replacement parts

Spouts, straws, sip tips and lids are all sold separately, so you never need to replace a whole tumbler because one small part is lost or worn. Shop replacement lids and parts. Every Yogi is also covered by our warranty — register yours here.
