Friends,
My clear glass shower cabinet is coated with limescale that is proving
almost impossible to remove. It is regularly cleaned with Cif Bathroom
spray. I have tried Lime-Lite, vinegar, Lemon juice and a half Lemon,
Brillo pad and in an obscure corner a scalpel!

It appears to be etched on to the glass, anyone any ideas?
