Black gunk in a sink drain is not always a sign of a clogged pipe. It could also be caused by a clogged stack vent. In either case, removing the stopper can clear out the problem. However, you should do this outside to avoid any risk of bacteria. Using protective gloves is also a good idea.

If you have noticed black gunk in your sink drain, you’re probably wondering how to get rid of it. This type of gunk is caused by bacteria that live on hand soap, hair, and other materials found in the drain. They also live in toothpaste and shaving cream residue. The best way to get rid of this gunk is to use a solution made of bleach, and let it sit for about 15 minutes before flushing it out. However, be aware that bleach should be removed from the drain as soon as possible, because if left for longer periods of time, it can corrode your pipes.

Pour in hot water and scrub away. Repeat the process several times a week. The vinegar is harmless and will not damage your pipes when used in small doses.
