Reading Time: 11 minutes Clogged and Costly: 20 Items That Will Destroy Your Kitchen Sink
This post may contain affiliate links. Read the disclosure.
You might not think twice about what goes down your kitchen sink, but trust me, you should. As a landlord with over 22 years of experience, I’ve seen countless plumbing disasters that started with a simple clog.
I’ve dealt with all kinds of plumbing nightmares over the years. The cost to fix these problems has ranged anywhere from $200 to over $3000. The most expensive repair happened when we had to dig up the concrete floor of a slab house because a pipe broke underground.
That’s an extreme case, but even smaller issues can set you back hundreds of dollars. It’s not just about the money either, plumbing problems can disrupt your daily life and cause a lot of stress.
Many people believe that having a garbage disposal solves all their kitchen waste problems. I hate to burst your bubble, but that’s simply not true. While garbage disposals can handle some food scraps, they’re not invincible.
Certain items can damage the disposal itself or cause blockages further down the line. It’s crucial to know what should and shouldn’t go down your sink, disposal or not.
In this article, I’ll share my hard-earned knowledge about the 20 things you should never put down your kitchen sink. I’ll also give you some smart alternatives for disposing of these items.

What to Do Instead
Before we jump into our list of sink no-nos, let’s talk about some better ways to handle kitchen waste. Proper waste disposal is key to maintaining a healthy plumbing system and reducing your environmental impact.
First, consider using a sink strainer. This simple device catches solid materials, preventing accidental disposal down the drain. It’s an inexpensive tool that can save you thousands in potential plumbing repairs.
For items like fats, oils, and grease, let them solidify and toss them in the trash. These substances might seem harmless when liquid, but they can cause major problems once they cool and harden in your pipes.
Composting is another excellent solution for many food scraps. Vegetable peels, pulp, and coffee grounds are perfect for composting. This method not only reduces kitchen waste but also creates nutrient-rich soil for your garden.
As a bonus tip, I’ve also created an article titled “Kitchen Hacks that Reduce Food and Financial Waste” that pairs well with this topic. These practices not only help your plumbing but also stretch your grocery budget and reduce overall waste.
Now, let’s get into the nitty-gritty of what should stay far away from your kitchen sink!
Grease and Oil
Grease and oil are major troublemakers for your pipes. When hot, they might seem harmless, but as they cool, they solidify and stick to the inside of your pipes.
Over time, this buildup can trap other debris, creating large, stubborn clogs that are difficult to remove. Instead of pouring grease down the drain, let it cool and scrape it into the trash.
