How to Clean Black Sludge in Sink Drain

Black sludge tends to build up in the sink drain pipes especially when the drain is not regularly degreased. It’s a combination of biofilm, grease, toothpaste, food waste, mold, mildew, hair among other substances.

Black sludge is a source of sink drain odors and slow-moving drains. If you see black sludge coming out of the sink drain, then here’re some tips to get rid of it.

Method 1: Use Boiling Water, Baking Soda and Vinegar

Since black sludge does not adhere strongly to drain surfaces, you can easily loosen and flush it using home solutions. Baking soda and vinegar are some of the most commonly used DIY cleaning solutions.

You will require baking soda, distilled vinegar, boiling water, plunger and gloves.

Steps

  1. Soak the sink drain by running boiling water through it. Plunger a few times as the boiling runs down the drain.
  2. Make a solution using one cup baking soda, one cup vinegar and one boiling water.
  3. Pour the solution down the drain and cover the drain opening with the stopper plug.
  4. Allow 5 to 10 minutes. The resulting bubbling reaction aids in loosening accumulated sludge for easier rinsing.
  5. Remove the drain stopper and flush with boiling water to push the already loosened sludge down the drain.

Method 2: Apply Drain Cleaner

Drain cleaners provide a very effective means of keeping your sink drains free of clogs. There’re different types of drain cleaners for both home and commercial use. Chemical drain cleaners work instantly while bioremediation drain cleaners take time to work.

When handling chemical drain cleaners, ensure that you wear rubber gloves.

Follow these steps to clean the sink drain using chemical drain cleaners.

  1. Pour the drain cleaner directly into the sink drain according to the instructions on the label.
  2. Insert the drain plug and allow the drain cleaner to act on the sludge for 20-30 minutes.
  3. Pour boiling water to flush out the already loosed sludge and drain cleaner.

Method 3: Remove Sludge Manually

Black sludge tends to adhere to top of the sink drain especially around the stopper. It appears as black slimy substance around the drain stopper. If drain cleaners or homemade DIY drain cleaners cannot get rid of the sludge, you can clear it manually.

Steps to Follow

  1. With your gloves on, remove the sink stopper by twisting and pulling it up. Some stoppers are locked by a horizontal plunger rod under the sink. In this case, you’ll have to free the stopper from the rod before pulling it up.
  2. Once the stopper is out, manually pull out the sludge and any other accumulated gunk.
  3. Wash the stopper with soap and hot water.
  4. Before placing back the stopper, clean the sink drain using your favourite drain cleaner, hot water and a flexible drain brush.

Conclusion

Fat, oils and grease clogs will attract all sort of substances that are tossed down the sink drain. This results in a black sludge which is not only disgusting but also a source of drain odors. To avoid black sludge buildup, it’s advisable to clean the drain with the best drain grease remover on regular basis.
