Earlier I heard something like “wrinkles in the copper can reduce the effect, something something the fluids get caught in little pockets and leave spots that don’t touch the copper.”
Have you heard anything about that and have any thoughts on that? A lot of the images I see of people coppering their doorknobs are particularly wrinkly, and I’m wondering how much effort to put into getting everything smooth.
