Drain Cleaning Do's and Dont's: 3 Things That Should Never Wash Down the Drain

February 26, 2026

Keeping drains clean and clear is a crucial part of maintaining a healthy plumbing system in your home. While it's easy to overlook, improper disposal of waste down sinks and toilets can lead to costly plumbing repairs. Regular drain cleaning and knowing what should never go down your drains is the first step in preventing clogs and other plumbing headaches.


1. Grease and Food Scraps

First and foremost, grease is a notorious culprit for drain clogs. When warm, it may seem harmless enough to pour down the drain, but as it cools, it solidifies, leading to stubborn blockages. Instead, allow grease to cool and dispose of it in the trash. Along with grease, food scraps like coffee grounds and eggshells should also be kept out of your drains. They can accumulate over time, contributing to buildup that often requires professional drain cleaning to restore proper water flow.


2. Non-Flushable Bathroom Items

In the bathroom, avoid flushing non-flushable items such as wipes, cotton balls, and dental floss. Even if labeled as "flushable," many products do not break down as toilet paper does, leading to clogs and potential sewer overflows. According to IBISWorld, the septic, drain, and sewer cleaning industry has grown at a CAGR of 4.5% over the past five years until 2024, highlighting the increasing demand for professional services to address such issues. Preventing these items from entering your plumbing system can save you both time and money.


3. Harsh Chemical Cleaners

Harsh chemicals, often used for cleaning, should also be avoided. They may provide temporary relief but can cause long-term damage to your pipes. Opt for safer, more environmentally friendly alternatives like vinegar and baking soda. Additionally, chemical residues can pose health risks and contribute to environmental pollution. Protect your plumbing and the environment by choosing gentler cleaning methods.


Taking simple steps to prevent inappropriate waste from entering your drains can maintain the efficiency and longevity of your plumbing system. By avoiding the disposal of grease, food scraps, non-flushable items, and harsh chemicals, you reduce the likelihood of clogs and the need for frequent drain cleaning. A little vigilance goes a long way toward sustaining a well-functioning home. Contact Mark's Reddi Rooter today to learn more about your drain cleaning and how to prevent issues.
