Stainless is (for the most part) non ferrous. This means it is not magnetic.

Here is a breakdown on Stainless Steel.

Rain water is full of contaminants. If you don't have access to distilled water you might try running your rain water through a water filter like Brita that has a carbon filter in it. This will remove 99% of the impurities in the water. I have run several units on filtered water with no coloring in the water after weeks of run time.
Can I use a fish filter with charcoal and fine sand, or is it too slim/weak?

Sorry, living in the lap of luxury, I can't imagine any place on the planet that does not sell drinking water in plastic bottles.
Our markets even sell gallons of distilled water for steam irons for less than a buck.
It's got to be better than rain water run through an aquarium filter.
Should not be difficult to fabricate a stove top still and boil a half gallon of water in a large pot, catch the steam, and let it drip down into a container.

Bottled drinking water and distilled water are NOT the same thing. Bottled water for sure has minerals and other things in it. Water that is well filtered can have much of the contaminates remove. Brita does a good job of this and I'm sure there are others. Don't know about aquarium filters but I doubt it.
