Regular cleaning has its merits. To keep drains in your home running freely — and absent of odor — try these methods:
Run hot water through the sink after each use. Hot water keeps oils in food products running down the drain, rather than building up on the interior surface of pipes, which can make drains sluggish and lead to clogs.
Throw a handful of baking soda into the drain and follow it with hot water. Baking soda is a terrific cleaning agent, and it’s also great for absorbing foul odors and leaving your drain pipes smelling like a rose. Okay, maybe not like a rose, but a lot better than they otherwise would.
Pour 1 cup of bleach down the drain and let it sit for 30 minutes; then chase it down with very hot water. bleach is a wonder cleaner. It contains acetic acid, which acts as an excellent solvent in removing buildup of crud in pipes.
If clogging is a regular problem at your property, try pouring 1/2 cup of bleach just before going to bed (to allow the solution to sit overnight, giving it more cleaning horsepower).
