You probably clean the coffee pot, but you’ll want to give the whole machine a deep clean every once in a while—NSF data show that coffee reservoirs where you pour water are even dirtier than toilet seats and toilet handles.
Clean it: Leaving the reservoir open when you’re done making coffee will help clear out the moisture germs love. Every now and then, clean the reservoir by filling it with equal parts water and vinegar. Turn on the machine so the vinegar cleans the carafe, plus eliminates mineral buildup in the machine’s pipes. Once the pot is done, “brew” a pot of plain water to eliminate any traces of vinegar. Don’t miss the 14 most germ-ridden spots in your own bedroom.
Your cutting board
University of Arizona researchers found that the average cutting board has 200 times more fecal bacteria than a toilet seat. A big culprit: raw meat, since many fecal bacteria originate in animals’ internal organs. So, the last chicken cutlet you diced? The tiny grooves your knife left in the cutting board are prime real estate for germs to get cozy.
Clean it: Wash plastic cutting boards with liquid dish detergent and water, then soak thoroughly in a solution of two teaspoons of bleach and a gallon of water. For wooden boards, do the same but use two tablespoons of bleach per gallon of water. Don’t soak overnight. Here are some more germy kitchen items you probably don’t think to clean.
