Interesting....

I think I will try the store distilled water first.

I think a still would be cheaper than a RO unit. Especially if you did not need high on demand volume

Our tap water quality here is not too good from a suspended or dissolved solids point of view and it definitely will leave spots if it dries. That is why the micro fiber towels are such an improvement for me. If I dry with them I get absolutely no spots.
