DIY Drano- Mix together 1 cup of baking soda, 1 cup of salt and 1/4 cup of cream of tartar. Measure about a quarter cup of the mixed powder and pour into your clogged drain. Pour two cups of boiling water into the drain, and let stand for about an hour, then run fresh water from the tap.
<3 UNCLOG DRAINS: Pour 1 cup of baking soda down the drain followed by 1 cup of vinegar. You can try heating the vinegar in the microwave for a few seconds before adding it to the drain. Wait 5 minutes before flushing the drain with 2 quarts of hot water~ I do this Monthly~
pour about a half cup of baking soda down the drain, and then pour in vinegar until it bubbles up to the top of the drain. I leave that for about 15 minutes, and then pour really hot water (not quite to boiling) down the drain. This will help disinfect the drain and clean it too.
