Getting rid of smell from sink drain?
My kitchen smells like a mixture of sour milk and rotten vegetables. The smell is coming from the sink drain. I've tried methods that worked in the past, like pouring boiling water down the drain, running the tap for a long time, a vinegar and baking soda rinse, and an overnight chlorine treatment. It's not working. Whan can I do to get rid of the smell? Is the stuff you use to unblock blocked drains good for cleaning away the stuff that is making the stink?
