While I do use the dishwasher for most everything (not the cats) I had not
really thought of the pH. Thanks to Francisco and others for pointing that
out.
Without applying it to "radio" and more to "kitchen" I have used "Cream of
Tartar" (tartaric acid) to polish up aluminum. Normally it is used for
making meringue as in lemon meringue pie.
I am reticent to deliberately doing alkaline <-> acid things to electronics.
That is probably one of the top benefits of things like Simple Green and
distilled water.
'long time ago I was tasked with figuring out the potential for corrosion on
circuit boards we fabricated. They had solder masks but we did not do
conformal coating. What brought it to management's attention was after the
folks in the panel fab area left an entire tray of circuit boards immersed
in the boiling side of a solvent cleaning tank all night long. (trichloro
type solution). We had other issues where the circuit boards were installed
in an enclosure, sealed with silicone RTV that releases acetic acid as it
cures (vinegar smell), those corroded as well*.
