Kitchen sinks are sometimes overlooked when homeowners come to clean the room, it has been suggested.Kelly Bothum of delawareonline.com noted that while homeowners focus on filling the dishwasher or keeping counters clean, they can ignore areas of contamination around the sink itself.Make it a habit to wipe down your sink and taps with soap and water or a mild bleach solution, she advised.It was also argued that people should make a habit of cleaning their food waste disposer gadgets as these can become a source of germs from food that gets crushed up in the mechanism.Ms Bothum was writing after an online survey by the Los Angeles County Department of Public Health found that one in seven homes would fail the health inspection administered to restaurants in the US city.Her comments also follow those of Lauren Woodgate, marketing executive at Erin Growing Media, who observed that people are increasingly growing their own produce in an effort to both save money and become more environmentally-friendly.
