Have always wanted to add something in here but never have. ...
Keep forgetting to buy *Draino* for my bathroom sinks, so looked up something online just for laughs ... and the blinking thing WORKS!!!
- 1/4 cup baking soda
- 1/2 cup white vinegar
- pour baking soda into drain
- follow with vinegar
- wait approx. 10 mins.
- then pour boiling water down the drain ( I used half a kettle full)
Just try it!
