First world problem –
How do i best get in and clean an old hip flask?

recommended brushes/ chemicals?

I don’t want whatever was in there last contaminating the new stuff through little bits of particles of either the cleaning products or the previous occupants

Half fill with water shoogle, pour out, repeat.

Fill.

I’ve cleaned similar things with a mix of isopropyl and salt, shake shake shake. then finish off with a few rinses of hot water.

Is it really that difficult?

Hot, soapy water, shake, empty, repeat. Then rinse with clean water, leave to drain. Maybe add a soak in there is there was some particularly stuff in there previously.

I usually just give a quick rinse with a bit of cooking whisky

What’s it made of? I’d be careful with silver, a bit slapdash with pewter.

If it were mine, and not silver, I’d fill it with hot water and put about a quarter of a Milton* tablet in there and leave overnight. Then I’d rinse it several times with near-boiling water, (while wearing nuclear grade PPE of course).

Last overnight soak with cheap gin or vodka, the sort only visitors get offered, and then in goes the single malt.

*Sold by chemists for cleaning babies’ bottles, and maybe other bits, and used by me for drinks bottles.

Both mine are stainless steel so just go in the dishwasher empty.

More so if i didnt finish all the previous whisky at the time and it tastes a bit cloudy.

Sorry that’s impossible. 🙄

Bicarbonate of Soda in a solution leave it 24 hrs then rinse out, works a treat on thermos flasks too.

Suggsey is right.

Yeh bicarbonate solution.. Also great for cleaning stainless steel sinks and what not.

When my on-the-go flask gets too heavily stained by tea, I use a cheap false teeth cleaning tablet, with very hot water. Leaves it all sparkly! I’d just break up one of those and fill with hot water.
They’re less than a quid from Wilco, if memory serves, worth keeping a tube around for cleaning stuff like flasks.

Pour in boiling water, place lid on, shake then empty followed a rinse. Not exactly a complex problem.

Don’t put bleach in stainless steel ones.

I think it’s OK if you wash it out with hot battery acid

Is that sensible advice scardeypants?

Pee in it, swill it around. Offer it around.*

*Nah, doesn’t really work, but now you all think I do that, I can safely leave my flask of 20yr old Glenmorangie on the bike without someone taking a crafty swig.

I use a cheap false teeth cleaning tablet

That works too but I don’t have any since dad died!

Oh, Sodium Metabisulphite (used for steralising brewing kit) also works.

“More so if i didnt finish all the previous whisky

when i say finish … i mean at the time.

tip the flask into a glass before finishing it and washing the flask. – can be cloudy sometimes if ive been using the other one for a bit…..
