hi there,i am trying to revitalise a kettle which had accumulated
some hard water deposits.

i boiled some undiluted white vinegar in it and left for a few hours.i
looked down the lid and the chrome coloured element was shiny as new.

to keep it new i decided to use bottled water in it from now on.

a few weeks later i noticed floating particles in my tea. i checked
the kettle to find quite a 1cm white formation growing on a part of
the element. in addition some areas of the element had green corrosion
marks.

Any ideas what is going on down there?How do you clean your kettles?
thanks,

Sam

Bottled water is *not* mineral free. If you want water with no minerals,
you need to buy distilled.

Personally, I'm still struggling with lime scale on our electric tea
kettle. Unfortunately, it's around the rim, and it's in a very difficult
place to soak in vinegar.

i lived for 25 years in a home in which we had artisan well water-
everything had had huge lime deposits-
i used salt as you did-
to solve the problem of the teapot-I switched to a glass
teapot-"Whistler"-the openings were wide enough for a dainty hand to clean
the inside and then used salt and rinsed thoughly

Or deionized, which you can also make at home with a cartridge gadget. Or
rainwater.

Sodium salts of ethylenediaminetetraacetic acid (EDTA) - for those not
afraid of "chemicals" - are a universal descaling agent that rapidly
chelates polyvalent ions like those in lime deposits. It's cheap at hardware
stores, but wear gloves and keep out of eyes. A spongeload may remove
deposits very quickly, or make a "poultice" in a rag or paper towel and
leave it for a while. Some dishwasher detergents are loaded with that,
zeolites, phosphates and other hard-water ion eaters. When I have crusted
old cookware, I usually just soak it for a few hours in hot water with a
cupful or so of the stuff. Watch out - can eat aluminum and some other
metals.

gross huh? Nothing you can do about it unless you heat your water via the
stove. Drinking distilled water is not supposed to be good for you.

Keep cleaning.

Dog Ma,

Is this stuff you're describing environmentally sound? After all, that acid
has 11 syllables, if I've counted correctly; a bad omen.

EDTA is a skin, eye and respiratory irritant. When I worked in a research
lab, we used it for a lot of different things. But it was always treated as
an irritant.

But it's not considered particularly toxic. Even so, it's not something I
personally want around my tea water. I've seen what it can do.

Thanks Derek. I knew eleven syllables couldn't be trusted.

Dog Ma is right - wear gloves. However, the warning about eating metals is
also accurate. EDTA is a no-no for:

copper, copper alloys, nickel, aluminium

It also reacts with strong oxidizing agents or strong bases.

While I take the whole distilled water thing with a grain of salt[0]
(no pun intended), there's little doubt that minerals matter. Here's an
interesting (although coffee-centric) link on the issue:

7C1AD905BDD0E1C748B93478611E804C


[0]I suspect there's some truth to it, as a person getting barely
adequate amounts of minerals and drinking lots of mineral-free
liquid might find themselves in a bad situation. But I don't
believe drinking distilled water is, in and of itself, the Big Scary
Monster some Web sites make it out to be.

The IUPAC name for table sugar is half a page long. Of course, people argue
about the safety of sugar. Arsenic is technically called arsenic. Draw your
own conclusion.

EDTA is pretty OK environmentally, and the grams you'd add to the kilotons
already dumped daily wouldn't matter anyway. It's also been used in common
foods for many years.

-But not quickly except with aluminum. What it will do is remove a thin
passivating layer of oxides, dirt, soap scum and scale to allow fresh
corrosion, as someone else here reported happening in a cleaned kettle.

True, but then, many things we use to prepare our aquariums for fish
are labeled "Do Not Use On Fish For Human Consumption."

And on fish FOR human consumption they are often used in higher
