The chemicals are very easy to get the oxalic acid is not too hard to find, citric acid is very easy to find.
I'm cheap so I just use air conditioner condensation when I need distilled water.

Also mining new platinum, palladium and rhodium for converters is incredibly environmentally destructive.

Palladium is at like a 16 or 17 year high right now, but rhodium and platinum are relatively low.
It was low enough to where I bought some rhodium, last year because it has gone up to $13,000 per ounce in the recent past.

Another important point, proper disposal of the used chemicals.
There is a very high likelihood that some of the ash in the converter is lead or cadmium bearing. So dump it down the drain. Waste water knows how to prevent the release of lead back into the environment since some houses still have lead or lead jointed sewer pipes.
