Is the drain in your shower blocked?
By Justin - Handy Hints
Remove any visible hair & soap from your drain, dry surrounding area. Pour 1/2 cup of household baking soda & then 2 cups white vinegar down the drain, this will cause a harmless chemical reaction that will loosen up what is stuck in your drain. After a few minutes, rinse with cold water for about 5 minutes. Do this every few weeks & your drain will stay unblocked & clean.
