Another vote for the mixture described in the utube video above. One litre water, 100gms citric acid, 30 gms Sodium Hydroxide, dash of fairy liquid. Works better than Evaporust, quicker much cheaper and does not appear to create the darkening effect of evaporust. Both chemicals available on line from the usual site courtesy of Jeff Bezos.

They are not, sodium hydroxide is caustic soda / lye - nasty and very alkaline. Sodium carbonate /washing soda is an alkali but more mild (one of the ingredients of sugar soap).
