How to clean a water bottle and its lid
Take the lid apart, brush every channel, soak the parts in warm soapy water or a cleaning tablet, then dry them upside down and apart. Do that weekly and rinse daily.

Questions this page answers
Will the lid get moldy, and can I clean it?
Mold grows where water sits in the dark: in gaskets, in straw channels, under spout covers. Weekly disassembly and a thin brush stop it. Black specks that survive a scrub mean the gasket is due for replacement.

Is it dishwasher safe?
Read your own listing and expect contradictions. Hydro Flask's Chug listing is a good example, with hand wash in the spec table and dishwasher safe in the bullets. CleverHiker lists the Owala as not dishwasher-safe. When in doubt, wash the bottle by hand and put the lid on the top rack.

Will water taste metallic?
A metallic or stale taste usually lives in the lid. Soak the lid and gasket overnight in warm water with a cleaning tablet. Rinse well, then let it dry before the next fill.

What to know
Daily: rinse and dry
Empty the bottle at night, rinse it with warm water and leave the lid off. Most smell problems start with a lid screwed onto a damp bottle.
A routine that sticks
Pick one night a week, put every lid and straw in a bowl of warm water with a tablet while you wash the dishes, and by the time the dishes are done the soak has done most of the work, leaving about a minute of brushing per lid. The habit matters more than the product. A bottle cleaned weekly with plain soap stays fresher than one cleaned once a month with the best tablets on the shelf.
Weekly: the full routine
Pull the gasket and the straw. Brush the straw with a thin brush and the spout with a small one. Soak the lid parts for 20 minutes in warm soapy water or with a cleaning tablet. Scrub the inside of the bottle with a long brush and rinse everything. Let the parts air dry apart before you put them back together.
Getting the gasket out
Most gaskets lift out with a fingernail or a blunt butter knife. Work around the edge instead of prying at one spot, and press it back evenly when it is dry. A gasket that will not sit flat is worn, and a worn one leaks.
Smell and stains
Coffee and tea stain steel; protein shakes and juice leave smells. Cleaning tablets are made for both: drop one in warm water, let it fizz, rinse. The Bottle Bright tablets we track are listed as free of bleach and chlorine.
Vinegar and baking soda
A tablespoon of baking soda in warm water, left overnight, lifts most smells. Diluted vinegar helps with hard water spots. Rinse well afterward, and avoid mixing the two in a closed bottle, since the fizz builds pressure.
Bleach
Skip chlorine bleach on stainless steel. It can pit the metal and wear seals. If a lid has mold that survives a scrub and a soak, a new gasket or lid is cheaper than the fight. Some makers sell replacement gaskets and lids for their own bottles, and for wide mouth bottles a third-party straw lid costs about $9, which is less than most people spend on cleaning products trying to rescue a lid that has already gone dark inside.
Drying matters most
Dry parts do not grow mold. Stand bottles upside down on a rack with the lid off, and hang straws and gaskets where air reaches them. A peg rack built for baby bottles works well for this.
Dishwasher rules
Lids usually go on the top rack. Some listings say hand wash for the bottle and dishwasher for the lid, and some contradict themselves. Follow the stricter line when in doubt.
Cleaning tools that earn their place

Today's Amazon priceMore questions
How often should I clean my water bottle?
Rinse daily and deep clean weekly. Clean it the same day after anything other than water.
Can I use vinegar to clean a water bottle?
Yes, diluted, for hard water spots and smell. Rinse well afterward.
Can I use bleach on a stainless steel bottle?
Better not. Chlorine bleach can pit steel and wear seals.
How do I dry a water bottle properly?
Upside down on a rack, lid off, parts separated.
What are the black spots on my gasket?
Usually mold. If a scrub and a soak leave them, replace the gasket.
Do bottle cleaning tablets work?
For stains and smells, yes. A brush still does the straw channels better.
How do I clean a straw without a brush?
Soak it in warm soapy water and flush it hard under the tap. A thin brush still does a better job, and a set costs about $9.
