Carefully sprinkle 1/2 cup baking soda down your drain, then chase it down with 1/2 cup distilled white vinegar. Cover or plug the drain to force the drain cleaner to work its way downward through the pipes, with a powerful chemical reaction that is very effective in clearing nearby clogs. (Tip: For shower drains, you can cover with a large bowl weighed down with water.) Let sit for an hour, then pour a kettle of boiling water down the drain. Repeat as often as needed until you’ve achieved a good drain flow; the good thing about this natural drain cleaner is that it won’t damage your pipes, so you can use it as many times as you need.
