Kitchen sink clogs typically occur due to the accumulation of grease and soap. This happens so frequently that hiring a professional adds to the monthly expenditure. However, if you know how to unclog a kitchen sink drain without a plumber, it will be a great save.

Why Sinks Clog

Have you ever wondered why your kitchen sink clogs so often? You are not alone. Many people deal with a clogged kitchen sink at some point. Let’s examine the primary reasons behind kitchen sink clogs so you can prevent them before they occur.
Food and Grease Buildup
Food scraps and grease are the primary culprits behind kitchen sink clogs. When you rinse plates or pans, small bits of food can slip down the drain. Grease from cooking may look harmless when it’s hot, but it cools and hardens inside your pipes.
Over time, these things stick together and block the water. But the question is how to unclog a greasy kitchen sink drain. You may notice water draining slowly or, in some cases, a completely clogged kitchen sink.
Soap and Foreign Objects
Soap can also cause clogs in kitchen sinks. Some soaps contain fats that mix with minerals in water. This forms a complex, sticky substance known as soap scum. Soap scum builds up and narrows your pipes. Sometimes, small objects like twist ties, fruit stickers, or even a spoon can fall into the drain.
These items get stuck and make a clogged kitchen sink even worse. You should always check the sink for any items that do not belong before turning on the water. If you know what causes kitchen sink clogs, you can take steps to prevent them.
