Grease accumulation in the drain is a major, yet, surprisingly very common plumbing problem, and almost everyone has experienced this inconvenience. Dealing with a drain that has been clogged by grease is also very frustrating because grease forms a mass that may take time to melt away.

The grease will also block the passage of water and lead to an overflow that can be quiet a mess if it is not taken care of immediately. Now, in addition to all this, it leads to an unhygienic and smelly mess that needs a quick fix. It has got to be the nastiest and hardest to deal with.

But, where does all the grease come from?

Grease, fat, and oils are common by-products of the cooking process. Other things that may build up in your kitchen sink are; food scraps, meats, butter, dairy products, rice, eggshells, etc., all of which can lead to a terrible clog in your system.

You may also be unaware of the fact that there are some soaps which contain grease. These are the fat-based soaps. They are either animal fat or vegetable-based soaps that will leave some residue behind after use, leading to a grease-based clog.

Now, even the most careful person who ensures there are no fats or oils or grease in their dishes before using the sink will still suffer grease clogs over time, because grease builds up. It settles in your pipes over time and eventually causes an ugly mess.

Where is grease most likely to build up?

Mostly, grease will clog pipes that are directly connected to the kitchen sink. Most especially the sink trap. FOGG – fat, oils, grease and grit are in water or soups, and these may appear to flow easily in your sink, but they are leaving some particles behind, which attach to the pipes.

Now, when you pass the hot liquids containing FOGG down the pipes, the liquid cools down and the grease solidifies when it is exposed to air. It then sinks to the bottom of the pipe and slowly coats it.

How to get rid of grease-related clogs:

Your dishwashing liquid can break up some grease, but only to a certain extent. This is because it is not designed for that particular use, and you will end up with the same mess if you decide to use this for clearing up the mess.

Hot water may also be used to try and clear out the grease related mess, but, it doesn’t always do a good job if the build-up is big and has accumulated for a long period of time. In some instances, the pipes may have a very thick layer that doesn’t melt easily and will require a more powerful product to dissolve it.

The best option would be to use a powerful drain cleaner, designed for eliminating grease clogs. A generous amount of this product will penetrate even the densest and hard grease in your pipes.

As it sinks down your pipe, it will also get rid of any other substances that may have attached themselves to the FOGG and caused the blockage. Here is a list of the best drain cleaners for grease related clogs.
