I get a small piece of kitchen towel soaked in vinegar wrapped around the
scaled area. Leave over night and then brush with toothbrush or scrape with
finger nail. If the scale is very heavy this may need to be repeated several
If you're doing them in situ - soak a rag in vinegar, and wrap around the
tap, then wrap cling film over the rag. Leave in place overnight, scrub
with old toothbrush, repeat if necessary.
If they aren't installed, put them in a container, cover with straight
vinegar, cover, leave overnight, etc.
The water here in north Hampshire is incredibly hard and I have to use
Kilrock on the chrome kitchen mixer tap once per month. It does say on the
bottle not to use it on/near enamel but to use the gel version instead. I've
never used it in a bathroom because the rest of my house runs from a
water-softener, a proper ion-exchange one not the magic coil ones :-)
I followed your instructions to the letter and wrapped a pancake left
over from pancake day on my taps. The cat (or some other piece of
wildlife) ate it some time during the seventh night and either died
or the pancake was regurgitated onto the floor (the effluvium has
legs and the cat is missing so I am not sure which it is). The scale
on the taps is still there but there is now a foul odour in the room
and tiles have started to peel off the walls.
I really cannot recommend this treatment.
Thanks all for your replies.
The taps are off the bath, so there is no problem with possible enamel
I've not heard of that......Is it widely available?
I think I have used Viakal in the past, but it was a long time ago and
can't remember how effective it was.
Most descallers are sulphamic acid (except those for use on enamel).
Cheapest way to buy it is probably a tub of Furnox DS-3 for descaling
heating systems. (Actually, it lists several other things you shouldn't
use it on, most of which I do without any problems.)
