KITCHEN SINK DRAIN CLEANER

1 cup table salt
1 cup baking soda
¼ cup cream of tartar
 

Mix these dry ingredients in a glass jar by shaking well. Use only ¼ of a cup at a time, directly down the drain, followed by 2 cups of boiling water. After a couple of minutes, turn on the faucet for a minute or so. This is a preventive maintenance formula and won't work when the sink is already clogged. Regular use will prevent a grease build up in the trap and make your sink smell better. How often? About once a month. Is it OK for the sink disposer side? No problem. Does it work in the bathroom? Not as well as on grease problems which is the biggest culprit in the kitchen drain. Keep the mix tightly sealed between uses.

(Also preventive maintenance but works on all home drains)
 

½ cup washing soda (larger super markets carry it in the detergent section)
1 gallon hot water
Turn on hot water faucet to run down the drain for a full minute. Turn off faucet and pour in mix. Wait for 10 minutes and then flush the line with hot water from the faucet for another minute.
