Use a toothbrush with a bit of the cleanser to clean the tight areas around the faucet, and the area around the drain.

Dry the sink thoroughly. Any water left on the surface will turn the flour into glue. Sprinkle a light dusting of flour over the sink. Use about ¼ cup (60mL) flour for an average kitchen sink. [6] X Research source Buff the sink in a circular motion with a soft cloth, focusing on the rim and drain where food might get stuck. Once grime is removed, brush the flour into a container and throw it in the kitchen trash. Too much flour can block the drain. [7] X Research source

Wash steel and cast iron cookware promptly. These materials may cause rust if left in the sink too long. [10] X Research source

Never use steel wool or carbon steel brushes. These materials can leave behind small metal particles that cause rust.

Most kitchen sanitizers that are not bleach-based contain quaternary ammonia. To confirm this, check the ingredients list for a chemical name ending in “ammonium chloride,” or for an abbreviation such as BAC, BZK, BKC, or ADBAC. [16] X Research source Bleach-based cleaners are not recommended, as they can corrode your sink if not rinsed off thoroughly. [17] X Research source Never let bleach come into contact with residue from other cleaners, as the reaction can produce dangerous gas.
