For some months now, we've noticed a light blue residual left in the bath below the taps. The water drips for a while after using the shower head (which we only use for washing the dogs) and then a few days later we notice the blue. It cleans off ok - just wonder what it might be?

It’s copper. Your water is aggressive to the copper in the system. It’s more noticeable in the hot water.
Simply, the hot water is dissolving the copper and then when it comes out and meets oxygen and the water dries off, you can see the residue against the white bath.
