Lemon juice is very bad for bronze coinage.

PS If lemon juice is an acid and baking soda is a base, wouldnt they just neutralize each other and leave a lemony pasty mess?
C.
Lol. Well sort of. Lemon juice is a strong acid And baking soda a weak base. So it would take a bunch of baking soda to neutralize a small amount of lemon juice. Maybe the spirit of the idea is to mix them, let's say 50/50, to make a less acidic solution, thus giving the
help of crud cutting of the acid without the same harshness on the
patina. Olive oil being a weak acid can do the same, but darkened the
patina, is messy, etc. You could also control the acidity of the lemony paste as well
I
still wouldn't try it personally.
