For daily cleaning: I combine a small amount of dish soap, baking soda, and hot water in a spray bottle (shown above). Spray on sink surface and wipe with a sponge, then rinse thoroughly.
Once a week I follow this process:
1. Wet your sink thoroughly making sure that all surfaces are wet. Then i sprinkle baking soda on the surface and scrub the entire sink with a toothbrush. Make sure to pay close attention to around the drain as well as around the faucet. These are the areas that tend to accumulate the most buildup. Rinse the entire sink and wipe down with a damp paper towel.
2. Next, soak paper towels in white vinegar and lay them in the sink so that they cover the whole surface. Allow them to sit for 20-30 minutes. Rinse thoroughly.
3. If your sink has a garbage disposal, place several ice cubes into the drain and run the garbage disposal. This cleans the grinding mechanisms in the disposal. Follow by slicing a lemon into quarters and place them one by one in the running disposal. (This cleans the disposal while making it smell like citrus).
4. Rinse the sink again with hot water and dry with a towel. Now your sink should sparkle and smell good.
**Always rinse and wipe down your sink after every use to limit the buildup and spots.
