Gary tackles two pressing homeowner concerns. First, he helps Chris, a listener with an eight-year-old deck, figure out the best way to clean and seal it. Gary recommends a two-step process involving a deck cleaner and a deck brightener to remove mold and mildew, and then discusses the importance of choosing the right stain for the job. Next, Gary takes a call from Jeff, who's dealing with a smelly toilet, and offers advice on how to identify and fix the issue, which may involve replacing the toilet seal or checking for bacterial growth in the drain.
