Every few months or so take the drain stoppers from the kitchen sink and toss them in the dishwasher when you run it. Does a great job cleaning the buildup especially from the bottom where it can get pretty gross!
Picnic-BBQ idea: place persihable foods like dips, condiments, cheese and meat trays, sandwich trays etc on top of ice in shallow pans or plastic bins to keep fresh and safe during a party. Don’t open and pour the ice, lay whole bag into a large shallow bins, like the ones used to store items under the bed.. Cover the ice with a dish towel then set trays of food on top! Keep covered from bugs and you will have a stress free picnic buffet!!
