Advice Flask cleaning

[Mr Fish]

Hi guys, I’ve got an old Coleman metal flask which I like as it’s sturdy and has good capacity.
But mainly because I can’t break it, as I always do with the glass ones.

The problem is there’s a real residue of coffee staining and sludge on it now, inside, that doesn’t give the coffee the best taste.
Now, I know a day or two soaking with diluted bleach would zap it clean, but the problem with that (I’ve found from experience) is I’ll probably be able to taste bleach for the next several trips.
I’m not worried about it being harmful in that quantity, but bleached coffee isn’t my first choice of drink!

Any alternative suggestions for a cleaning agent? Baking soda maybe? I’ve never used the stuff but heard it can clean?

 

[Thrasher]

Bicarb, steradent tablets or dishwasher tablets.

 

[Reevsey]

Try white vinegar .

as said above, Steradent tablets. I`ve got about three tubes at any time as I put older rod guides into them to clean them up, works a treat.

Milton.Clean baby feeding bottles with it.Or the equivilent cheaper version sold by Home Bargains.Works a treat.

Many thanks folks. None of those products I’ve ever bought, lol, but I assume things like steradent would be on the shelf in supermarkets

Get some dentures and discover for yourself.Never mind picking other peoples brains.Nothing like firsthand experience.

You will have sparkling white teeth if you put in your coffee.

You will have sparkling white teeth if you put in your coffee.

But end up foaming at the mouth.Bit like Rabies.

This be the stuff I use on my stainless flask, bloody brilliant stuff, try local home brew shop or go online chap

I always used to use Soda Bicarb for my old work flask, but as others have said, Steradent and some of the other suggestions should work. Used to put in about 2 tablespoons of Bicarb & fill to the brim with boiling water, and leave it overnight. Rinse thoroughly before use! We picked up a big bag of Bicarb in France, and it seemed to work much better than the UK stuff, but almost run out now!

Put 2 or 3 of the tabs into the flask then pour boiling (or almost boiling) water into the flask. Dont fill right up as the tabs will foam. Any supermarket will have them as well as any chemist, I get mine at the local corner shop. Dont screw the cap back on or you could have something akin to an IED

SODA CRYSTALS

akin to an IED

That will get picked up on by those watching joe carp.Watch your back.They will come a knocking on(or smashing in) your door.

 

[Tournamag]

Vanish works well cleans anything use it on fishing rags and anything else that needs Nuking! then rinse out well after sparkling clean.
