Occasionally I clean my coffeemaker by running white vinegar through it. After the vinegar has been processed, I pour a little baking soda down my bathtub drain. Next, I pour the pot of hot vinegar into the drain and plug it up.
The reaction between the baking soda and hot vinegar cleans the drainpipe of built-up soap scum and hair. By plugging the drain, I funnel the chemical reaction into the pipe instead of letting it bubble back up into the tub. I use a rubber stopper in my tub and hold it in place with pliers to avoid being burned by the hot vinegar.
This saves me money by not having to buy expensive drain cleaner. And, even better, I’m helping the environment by using a natural product to keep my drain clean. Susan
