Kitchen drains commonly get clogged due to the accumulation of grease, food particles, soap scum, and sometimes foreign objects. Over time, these substances can stick to the inside of pipes, gradually narrowing the passage until it becomes blocked.

To prevent clogs, avoid pouring grease or oil down the drain, scrape food scraps into the trash before washing dishes, use a sink strainer to catch food particles, and regularly flush the drain with hot water or a vinegar and baking soda mixture.

While chemical drain cleaners can provide a quick fix, they’re not recommended for regular use as they can corrode pipes over time and are harmful to the environment. For safer alternatives, consider enzymatic cleaners or mechanical methods like plunging or snaking. For persistent clogs, it’s best to call a professional plumber.

This largely depends on your usage. For most households, having the kitchen drain professionally cleaned every 1-2 years is sufficient. However, if you use your kitchen heavily or have frequent problems with clogs, you may require more frequent professional cleaning.
