In this hour of "At Home with Gary Sullivan" he covers various home improvement topics. Gary discusses the importance of removing rock salt residue from concrete after using it to melt snow and ice. He recommends alternative ice melters like calcium chloride and magnesium chloride, which are less corrosive. The conversation also touches on plumbing issues, including a caller's problem with a clogged drain and a toilet that's not flushing properly. Gary offers advice on how to fix these issues, including using a snake to clear the drain and adjusting the water level in the toilet tank.
