Yes Jean, I would have thought that bicarb and lemon juice together would have reduced the acidity, but Marco used it, and apparently it worked. Maybe it was just the bicarb and brushing that produced the result, bicarb just by itself is a powerful cleaner.

What effect do you think sulphur and salt together might have on ferric material?
