Exactly Where Does Grease Originate?

The following elements are mostly the main causes of grease.


Meat, cheese, grains, coffee grounds, vegetables , and eggshells cooked in oils all produce grease, fat, and oil as byproducts. Almost anything used in the kitchen increases the risk of a pipe becoming clogged with grease. Oil buildup in the drain pipe can occur even if you're careful about keeping the drain hole clean.


Large Food Particles

The p-trap, a curved pipe found under the sink, can become clogged with large food particles or vegetable peels.


When used in the kitchen, soaps' animal or vegetable fats function similarly to grease, oil, and fat. The soap grease and residual food grease combine to build a fatty obstruction in your drain that stinks to high heaven. (While fat-free soaps are commonly available, few customers know this.)
