Looking for some recommended methods for removed cake from a rusticated rim. Recently got a nice estate castello old sea rock for a good price. The price came with some work to do. My issue is that all I find for rim cake is using saliva with q-tips, but this is almost always for smooth rims. Some of the cake at some points is thick enough to hide the rustication, but I don't want to gouge at it fearing that I will damage the rim. How should one approach this? Thanks!
