Black specks in the caulk
When washing my TT today, I noted that along the front where the upper aluminum face of the TT joins the lower aluminum armored plate, the bead of caulk that runs the width of the TT (see pic) has a significant number of black specs. that appear to be embedded in the caulk that will not come out with cleaning (I tried soap/water and also Walmart mean green). If I lightly rub a screwdriver across these black specks, very small flakes occasionally rub off. I am wondering if it's some type of mold since it's a ledge that can collect dirt and water.
Has anyone experienced this? Should I remove this caulk bead and re-apply a new bead?
Any thoughts would be appreciated.
