According to hygiene expert Lisa Yakas, the sink in the kitchen is one of the dirtiest places in the house. It may be just a little cleaner than the sponge or dishcloth, but that doesn't mean you can mess up the sink.
Yakas recommends cleaning the sink thoroughly once a week. But… have you been working on raw meat or scrubbing dirt from potatoes? Then you have to do extra cleaning in between.
How to clean the sink
Remove all food residues and then scrub with warm water and soap. Then use some cleaning vinegar or a disinfectant spray before rinsing the sink for the last time.
