If your drain is starting to slow down or getting clogged with gunk, there are a few things you can do to dissolve the gunk and get your drain flowing freely again.
One option is to use a commercial drain cleaner. These products contain harsh chemicals that can break down the gunk in your drain. Be sure to follow the instructions on the product label carefully, as these products can be damaging to your pipes if used incorrectly. If you have a septic system, you'll need to choose a product that is safe for septic systems.
Another option is to make your own drain cleaner using natural ingredients that are safe for both your pipes and septic system. One recipe calls for mixing ¼ cup baking soda with ½ cup vinegar and pouring it down the drain. Let it sit for an hour, then flush with hot water. Another recipe calls for boiling water and pouring it down the drain, then adding ½ cup baking soda followed by ½ cup vinegar. Let this mixture sit for 15 minutes before flushing with hot water
