Do you cringe at the thought of cleaning out a mayonnaise, peanut butter, or mustard jar to reuse it? Or worse, getting the residue out of a slimy vase, decanter, or container? There is an easy way to handle these jobs. Fill the item with equal parts vinegar and warm, soapy water and let it stand for 10-15 minutes. If you’re cleaning a bottle or jar, close it up and give it a few good shakes; otherwise use a bottle brush to scrape off the remains before thoroughly rinsing.
