My sink emits a whiff of something when hot water is used. It isn't the water itself. I've used bleach-based drain cleaners and soda and vinegar to no effect. I took a good look down the drain and found the attached. Whoa.
It isn't scoopable. It feels more like soft rubber and is a single piece. Is it a wrecked discolored mildewy seal or robust biofilth?
