Washing Machine Cleaning Mistakes That Could Be Damaging Your Washer

We often think of washing machines as “self-cleaning” appliances, but in reality, they need regular care to stay efficient and hygienic. A well-maintained washer not only lasts longer but also keeps your laundry smelling fresh. However, many people unknowingly make cleaning mistakes that can shorten their machine’s life or reduce its performance. Let’s break down the most common washing machine cleaning mistakes and how to avoid them.

1) Using Too Much or the Wrong Type of Cleaner

More detergent doesn’t mean cleaner clothes—or a cleaner washer. In fact, excess detergent can leave behind a sticky film that traps dirt and bacteria inside the drum, hoses, and seals. This residue builds up over time, creating unpleasant odors and even mold growth. Harsh chemicals, bleach-heavy products, or abrasive powders can also damage sensitive components like the rubber gasket or pump.

Better approach: Use a cleaner that is safe for all washing machines, including HE, top load, and front load models. A slow-dissolving, residue-free tablet ensures the cleaner reaches hidden areas without harming delicate parts.

2) Neglecting the Washing Machine Filter

The filter is your washer’s first line of defense against lint, hair, and small debris. Over time, these can clog the filter, forcing the motor to work harder, reducing efficiency, and causing slow drainage. Ignoring filter maintenance is one of the fastest ways to reduce your washer’s lifespan.

Better approach: Check your machine’s manual to find the filter, which is usually located near the drain pump. Clean it at least once a month, or more frequently if you often wash heavily soiled laundry or pet bedding.

3) Cleaning Only Visible Surfaces

Wiping the door and detergent drawer is a good habit, but it’s not enough. Bacteria, soap scum, and mineral deposits collect behind the drum holes, inside hoses, and along internal surfaces you can’t see. This hidden grime can affect water flow, cleaning performance, and even lead to mechanical issues.

Better approach: Combine regular surface cleaning with a monthly in-drum cleaner cycle to reach these hidden spots. This prevents buildup in areas you can’t access manually.

4) Over-Reliance on Vinegar and Baking Soda

While vinegar and baking soda are popular DIY cleaning solutions, they aren’t always ideal for modern washers. Vinegar is acidic and can degrade rubber seals over time, while baking soda can clump with detergent residue, creating more buildup rather than removing it.

Better approach: Use a pH-balanced cleaning product designed for washing machines. This ensures effective residue removal without risking corrosion or seal damage.

5) Ignoring the Drain Hose and Pipe

Most washer cleaning routines overlook the drain system. Over months and years, detergent residue and lint can collect in the drain hose, causing blockages or slow draining. This can leave water standing inside the machine, creating a breeding ground for bacteria.

Better approach: Run a cleaning cycle with a washer-safe descaling tablet every month to keep water pathways clear and reduce odor risk.

6) Waiting Until the Washer Smells

By the time you notice a musty odor, bacteria and residue have already built up inside your washer. Treating the smell without addressing the root cause usually results in it coming back quickly.

Better approach: Prevent odors before they start by cleaning your washer on a set schedule—monthly for most households, and every two weeks for heavy use.

Building a Smart Maintenance Routine

• After every wash: Leave the door or lid open to let moisture evaporate. Wipe the gasket and detergent drawer to prevent mildew.
• Weekly: Do a quick visual check of the filter area and wipe surfaces.
• Monthly: Run a cleaning cycle with a dedicated washing machine cleaner to flush away hidden residue and keep components fresh.
• Quarterly: Inspect hoses and connections for leaks, kinks, or wear.

Why a Compatible Cleaning Tablet Makes the Difference?

Not all cleaners are formulated with your washer’s materials and design in mind. A high-quality tablet like Reliqu Washing Machine Cleaner is safe for HE, top load, and front load machines, dissolves completely, and reaches deep into the drum and drainage system. This helps prevent the most common cleaning-related damages while keeping your washer running at peak efficiency.

Final Thoughts

A washing machine is an investment, and avoiding these common cleaning mistakes can help it run better for years to come. The key is balance - don’t over-clean with harsh products but also don’t let buildup sit for months. With the right products and a simple maintenance schedule, you can keep your washer fresh, efficient, and odor-free.
