Household Hints Garbage Disposal Problem: Disposal doesn't seem to chop the food well or drain has an odor. Fix: Fill an ice cube tray 1/2 full of vinegar and 1/2 full of water. Once the cubes are frozen, place them down the disposal 2-3 cubes a week for about a month and this will not only sharpen the blades, but keep your drain clean at the same time! Cooktop/Oven Range Problem: Gas Burner on the cooktop is not heating evenly. Fix: Clean orifices on burner with a toothpick, toothbrush or pipe cleaner. This will increase gas flow, provide an even flame and help burner light quicker.
