We have been running a water softener for over 7 years now and it does
make a great difference.
The water is soft and shower gel etc. foam easily.

However over time the plug hole of the shower bath has built up a white
deposit.

Has anyone else experienced this?
On line search isn't very helpful.

I assume it may be one of the soluble salts in the water which has become
less soluble and slowly built up, but that somehow doesn't seem right.

If it's not removed with descalers, then it's probably Calcium Sulfate,
sometimes known as 'permanent hardness'. We have it too.

As far as I can tell, there's no easy chemical way to remove this. We
have successfully and gently used wire wool on chromed parts and
porcelain. Some say this shouldn't get through the softener, but a
small amount does.

To minimise it, get into the habit of mopping up where water drops
collect - just a wipe with a cloth can reduce the amount of water and
hence eventual scale by (a guess) a factor of a hundred.

Getting it off resin shower trays is trickier because obviously you want
to avoid scratching. Ive done it once, but now we squeegee this after
use - a soft silicone squeegee is much kinder than a window cleaner's
hard squeegee. Before we move I'll probably go over it again with wire
wool, or maybe some sort of buffing disc with maybe chalk.

Reducing the amount of evaporating standing water is key.
