I use Wildwinds for identification. I buy only uncleaned coins, cleaning them and identifying them soothes my 'tism.
First I soak them in distilled water, then scrub with a soft toothbrush and toothpicks.
If there's bronze disease, I use a 1% solution of sodium sesquicarbonate for about a month. After that soak, I do 3 quick two day distilled water soaks. Air dry.
Picrel is a bronze that had bronze disease (contact with chloride ions). The patina was removed, but it won't disintegrate anymore)
