Hello, Yesterday a guy took some silver ingots out of the pickle,
dried them clean and started rolling. This evening I noticed that
appr. 30 per cent of the rollers of my rolling mill look brown. I
took turpentine to take the oil off (he had put oil of them, as he is
supposed to do). I then took a piece of cloth, made it wet with
water, sprinkled sodium bicarbonate on the rollers and started to
whipe. After that, I whiped the rollers perfectly dry and put a very
generous amount of oil on them. Is there anything else I should do?
I am almost perfectly sure that some Sparex got to my rollers.
Kind regards, Leach
