Topic: Metal Cone Coffee Filter (8 msgs / 108 lines)
1) From: Tim Hoke
My post has to do with the metal cone filter which I just bought from 
Sweet Marias.  Is it OK to leave the metal filter in when running some 
vinegar through my coffee pot?
I get sediment build up with the water in San Antonio.
Thanks.

Good question; I would say yes as long as you do not leave it there for a LONG period of time.
Why not just use some Dawn dish detergent to clean/soak your filter with? Likee you are washing it as a soup bowl etc.

Tim,
The instructions with my coffee maker and a gold mesh filter says to=
 remove the filter when descaling the coffee maker.  Don't know what the ac=
id in the vinegar would do to the gold filter. I have not had to descale my=
 new coffee maker because of the hard San Antonio water.

Gold is one of the Noble metals that is nonreactive even with Aqua Regia, a
mixture of concentrated Sulphuric + Hydrochloric acids.
If the Gold filter is really metallic Gold or even plated with Gold metal,
your only worry should be a mechanical scrubbing of the filter. None of the
snake oil that cleans up espresso machines would bother real metallic gold.
But all the crap and corruption that came out would get stuck in the filter
and you'd want to reread paragraph (2) above.

Con Sulphuric + Con Nitric acid = Aqua Regia. Won't touch Gold.

If the metal is actually gold or gold-plated, the vinegar shouldn't
hurt it.  However, for the filter unit, a mild detergent would remove
the stale coffee oil crud better than vinegar.

I think that aqua regia is actually concentrated nitric and
hydrochloric acids.  Very nasty stuff.  And I believe that it will
dissolve metallic gold (along with any other crud from coffee making).
 I think that there are only a few metals that aren't oxidized by aqua
regia, iridium is one of them.  If you had the equipment and the money
you could make a nice iridium plated Swiss gold filter -- just what
every coffee geek needs!  I wouldn't recommend playing with aqua regia
unless you know what you are doing and have proper protection (don't
breathe the fumes).
