Cleaning straws and gaskets

It is not the body of the bottle. Stainless steel walls get rinsed, dry quickly and are visible. The problems live in the narrow tube of a straw, in the groove a gasket sits in, in a flip hinge, and in the thread where the lid meets the body and a film of water sits in the dark.

Every one of those is removable on most of the vessels in this catalog, and the whole of good practice is: take them apart, wash them apart, and dry them apart. Reassembling a wet lid is how a clean bottle becomes a smelly one.

A straw is a long narrow tube that never gets touched by a sponge. It needs a straw brush, which is a different object from a bottle brush, and it needs to be stood up to drain rather than laid in a drawer.

A flip straw adds a hinge and a cover. A covered straw lid adds a second surface. Both are improvements for carrying and additions to the cleaning list, and the listings that state them are telling you about both consequences whether they mean to or not.

On most lids the silicone ring lifts out of its groove with a fingernail. Under it is the surface nobody looks at. Once a month is a reasonable habit for a lid in daily use, and after any drink that was not water it is not optional.

Keep each gasket with the lid it came from. Swap lids share threads more reliably than they share seals, and a gasket in the wrong groove is a leak that gets blamed on the bottle.

One tumbler listing in this catalog states dishwasher safe construction. Every other listing here says nothing, and nothing is not permission. The manufacturer instructions decide, and a top rack claim does not cover the vacuum seal on every design.

For kids bottles the same cleaning rules apply and nothing else changes. This site gives no age guidance and makes no claims about children. Adults supervise use and do the disassembly; the CPSC is where product safety notices and recalls are published.
