I live in an apartment, that has really inefficient old appliances. The worst being the
dishwasher. If I leave just the littlest bit of
food on a dish, it'll stay or wind up on my
glassware. Yuck! This is what I do now to fix this problem. If I have stuck on
food (like hard stuck on
food left on the counters for hours), I add to the
dishwasher, my
dishwasher tablet, and fill the dispensers with cheap distilled
vinegar. It's roughly a 1/4 to 1/3 cup of
vinegar for a full load (roughly the amount of
dishes 3 meals a day x 2 days x 3 people). My
dishes come out sparkling and squeaky clean every time!
