You do - just buy them in the supermarket. On their own they're
common, all Cillit Bang has done is to mix them up together.

Mary will probably use formic acid instead, made by boiling up an
anthill, and a detergent made by pressing the oil out of beech nuts.

Hi,

Have had great results on a badly 'cemented' kitchen tap with a formic
acid based kettle descaler.

I wrapped a couple of layers of loo roll round it (!) before pouring
the descaler on so it wouldn't run off straight away.

Even though using a small amount didn't make the scale disappear, it
weakened it enough to be scrubbed off with minimal elbow grease.

cheers,
Pete.
