A Great Natural Drain Cleaner

Apple cider and baking soda make for a great drain cleaner.
Try 2 to 1 table spoon ratio of apple cider to baking powder to create a foam and pour it down your sinks, toilets, outside drains.
After 15 minutes flush through with hot water and your done.

You can even bath in this stuff to detoxify your skin and it will clean the bath after you :).
