degreasing

[Guy Van de Poel & A. Kalus]

I will try (clothes) dryer water, as that should not contain any ions
(chemicals) (or de-ionised water).
However I do not expect that to be any better, as also others found that it
was the condensation dripping on the specimens causing the greenish
coloring - condensation which should not contain the chemicals in the water
straight from the tap.

But nobody seems to be aware of a cure ?

Guy.
