I guess there's an easy answer which I ought to know, but I thought
I'd ask the experts who hang around here

Our shower head needs cleaning fairly frequently - by pushing a pin
thru each of the little holes. This is obviously due to scale building
up as the water flows thru. For a short time after the head is cleaned
we get a wonderful shower (it's a pumped circuit), but it doesn't take
too many showers before it's off with the shower head to clean it up
again.

Is there a recognised way of keeping the shower head from furring up
like this?
