Wide mouthed Stainless thermos..

I find that baby sterilizing tablets are also good to sort out stinky thermos and water bottles. Just rinse well after.

I used to use those to clean my double-walled steel work mugs, they both developed a leak in the inner . I think it was where the tablet tended to sit while fizzing.

Got a bog standard one from Argos. Just rinse well, soak in hot & soapy, then wash thoroughly - a big bottle brush can help with that. If it smells, I leave it standing filled with water & a tablespoon of bicarb.

Anything I have like that, if it's stored long term, it gets a tablespoon of bicarb dropped in it and the lid set on top but not done up tight. Easy enough to rinse it out before use & stops it getting that musty smell.

I love that.
"If in doubt, drop a tablespoon of Bicarb in"

Motto for life.

Good stuff, bicarb

(So are vinegar & salt, come to that, much underrated!)

BTW I have a bog brush (bought new for the purpose) I use as a bottlebrush because regular ones are a bit skinny

Brand new brush usually for behind radiators or blinds here. I just use snips to take off what I want lengthwise, then bend the ends round so the bristles don't escape/there are no sharp bits.
