flask cleaning

aj said:

i have bought some bicarbonate of soda to clean my half litre coffee stained
flask,any idea how much i should put in & with warm or cold water?
thanks.

Every so often I use Sodium Bicarb to clean my flasks and I can never
remember what solution I use.

For a half litre, I reckon one rounded dessert spoon and warm water.
The important thing is to leave it for AT LEAST 24 hours. Peeping
seems to stop it working!

I'm sure there'll be a household tips page somewhere on t'internet but
that sounds like about what I'd do.

I use baby bottle sterilising tablets. I seem to have some left over
from when the kids were that age. (They are now technically no longer
children!)

IIRC sodium bicarbonate is unusual in that it is more soluble in _cold_
water.

Though as long as there's enough hot water to dissolve it I'd guess
that the hot water will do a better job of helping to eat dirt, and
in time it will become cold water in any case, so might as well go
with hot, I think.

With the smaller flasks we've foung standing them upside down in
the dishwasher does the job very well, though of course you need a
dishwasher for this!

Yes, that could be true. I haven't a clue what you're *supposed* to
do. 'ang on, I'll have a quick shufty......

http://www.thermos.co.uk/care.php says "For excessive staining use of
household stain or scale remover is recommended. To remove difficult
stains fill your flask with hot water, add one teaspoon of bicarbonate
of soda and secure cap. Soaking overnight produces excellent results.
Always rinse before re-use. "

Being a Yorkshire man, the stain enhances the flavour of the drink, so my
flask never get cleaned. I always remember my mother saying never to clean
the tea pot out as it would ruin a good cup of Yorkshire tea. But, I
suppose with today's healthy drive for everything to be sterile and germ
free, a goood clean will ensure a long life!

Being the active ingredient in baking power, it decomposes to sodium
carbonate, water and carbon dioxide if it gets too hot, so luke warm
might be best.

Or use the tablets for cleaning "false teeths". Works excellent.

Interesting that. My English grandma never washed out a teapot and my German
grandma never washed out a coffee pot!.

I do wash out my flask. I've tried bicarb, Sterident and sterilising
solution (as purchased in brewing shops). I find the latter is best (Sodium
Metabysulphite or Sodium Metasilicate).

Since you pour (nearly) boiling water in before use, I can't see
sterility can be much of a problem.

dosent leave a taste either

During a spell of several months when I smoked a pipe I discovered that
they taste foul until they are well cindered up. If you scrape em out
too much you are back to square one.

Of course not, and I expect that's all your own hair too, isn't it?

Interesting that so many blokes responded to this one Judith ... don't you
think?

Are they as good at home doing the dishes?
