Remove all dirty dishes and any leftover food from your sink. There should be nothing in it as you begin scrubbing your sink.
Wash down the entire surface area of your sink. Use a gentle soap, soft cloth, and warm water to clean the faucets, drain, and outer rim. Do this every time you use the sink, which includes after preparing meals or washing dishes.
Run hot tap water into the drain. This will help eliminate bad odor and soften any gooey materials that may be lurking in the drain. Be sure to wet down the entire sink through this process. Do this several times a week.
Pour 1 tsp. (5 ml) of baking soda and 1/4 cup (60 ml) of lemon juice over the surface of your sink, and in particular down the drain, at least once a week. Let this mixture stand for approximately 10 minutes. Use hot water to rinse away any leftover residue.
Mix together 1/2 cup (120 ml) of baking soda, 1/4 (60 ml) cup of lemon juice, and pour the solution directly into your sink drain. Once the mixture is in the drain, pour down 1/2 (120 ml) cup of white vinegar. Use the combination of these ingredients once a week to help break up stubborn clogs and sanitize the drain.
Rinse your kitchen sink thoroughly with hot water after all cleaning routines.
