But before we present the best drain cleaner for grease, let’s first understand the basics of grease, its accumulation, where it comes from and how you can avoid it in the future.

So where does grease originate?

 Everything contains a considerable amount of grease, oil and fats. Many of the foods we take or use including detergents, soaps, egg shells, grinds, butter rise, coffee, food scrapes, dairy products and meat contain fats, oils and grease. During cleaning of utensils or even bathing, the grease flows into the drain pipe, where it accumulates and clogs the drain. Sometimes you won’t even know it is accumulating. Signs of accumulation emerge only when it’s too late and the grease has attached to the drain pipe. Some of these signs include slow water drainage, gurgling sound, and bad smell coming from your drain. Even the soaps we use contain grease, especially fat based soaps, given that most soaps are either made of vegetable oil and animal oil –all of which contain grease which has a potential to clog your drain. The most annoying part is that you won’t even know that there is grease in your drain until one day you have a bad smelling sink or one that is overflowing.

So Where Is Grease Likely To Accumulate?

In most cases, grease will accumulate in pipes that are directly linked to your kitchen sink or bathroom sink. If you often drain hot water into your sink, you will realize that the grease accumulate in the sink trap. It also tends to accumulate at the base of the sink and in the drain pipe. Overtime and as you continue to drain the fats and oils into the sink, the grease will solidify in the drain pipe and harden further. The further you drain the fats, the more the grease accumulates in the drain pipe. Sooner or later, the grease will become bigger and bigger clogging your drain pipe, reducing the water flow and causing either a blocked sink or a busted drain pipe. So when you see signs of grease related clogging, it’s time to select the best drain cleaner for grease, that will not only clear the clogs but also has a long lasting effect.
