Hi
Go to your local janitorial supplier and ask for a 5 ltr limescale remover, I used to use a purple one, think it is from selden.
Now I use toilet descaler, it is much more powerful (£1.20 at tescos) it is practially instnataneous, you can apply with a green scourer onto shower galss, taps, sinks and tiles and rinse straight away, buff up with glass cleaner and kitchen towel.
Regards
