You can prevent clogs in your kitchen sink by following some simple tips. The number one thing to remember is never put grease or oils down the drain even if you have a garbage disposal. After each use toss some baking soda in the sink then run hot water through the sink. Once each week you can plug the sink, fill it up and then drain. This force will push any gunk out of the drain. Once a week you can pour bleach down the drain to dissolve clogs. Just a few regular maintenance steps will help avoid larger problems.
