The easiest cheapest way to save your steam iron or houseplants
from hard water minerals, is to use rainwater.

Rainwater can be fairly acid nowadays.

Failing that, if you have
an old-fashioned freezer that requires periodic defrosting, bottle
some
melted ice. Both waters have previously evaporated then condensed
again,
which means they don't contain any appreciable amount of groundwater
minerals.

That sounds clever.
