Start w/dry drains. Put 1/2 cup baking soda & 1/2 cup vinegar down drain, close drain or cover w/cloth. Let sit 30 minutes & flush down w/tea kettle full of boiling water. Good for toilets & shower drains too
Every month or two, give the pipes a good preventative cleaning to keep them clear of grease, oil, and hair clogs. Pour 1/2 cup baking soda down the drain, followed by 1/2 cup white vinegar. The mixture will foam up. Let stand for a few minutes to dissolve fatty acids, then pour boiling water down the drain to wash out any clogs.
