I have not tried it yet, but I am thinking that if you added some baking soda to some water, and used that instead of tap, you might help prevent such things.

I think Magpie is correct - I have read of other people using this trick to prevent staining and quick rust formation. Baking Soda/Bicarb/Bicarbonate of Soda/Sodium Bicarbonate - they are all the same thing if anyone wants to get some.

With some places, the tap water isn't of consistent quality - something to do with well water/aquifers: the levels go up and down according to climate and the water property changes with the volume of water.
