Our customers have found that a good alkaline cleaner, used as hot as
possible, and as long as possible, perhaps even used as an electrocleaner, to
shorten the process time, is the key, after that any weak acid solution,
Sulfuric is great, then rinse and plate.

I can give you more information directly, or contact Dynavest, or their
subsidiary Comacraft, with offices in Penang, KL, Manilla, and Singapore.
