Since I purchased this home a few months ago, we've noticed water from the sink can sit in this corner and possibly grow fungus or just leave mineral residue when it dries. We have tried to keep it brushed out as we figure out what to do with it.
Note that the edge against the painted wall (green arrow in photo) does appear to have silicone caulk while the edge I'm asking about (red arrow) has nothing.
I want to apply clear silicone caulk but
- I've never had stone countertops before and I'm not sure what kind of stone this is either and
- I've had countertops where is corner is missing caulk near the sink, but this corner has zero caulk all the way across two walls
Is it OK to silicone this edge between the counter stone and backsplash stone?
