Scale remover (available all over the place) is the correct tool for
the job. Why anyone would want to **** about pouring diet coke
around a bath is beyond me.

Hmm, don't know how the % of active chemicals compares in the two but:

Tesco value cola 9.5p/litre
Viakal (limescale remover) £5.36/litre

that's knocking on 60x as expensive vol for vol, maybe I'll give the
cola a go.

Except that lime scale remover will stick to the surface and is
concentrated enough to do some good

A fiver sounds a lot for a litre of limescale remover - 5 litres of
conc phosphoric acid costs less than 20 quid

Which aisle at Tesco?

Just next to the hard spirits
