How to Clean the Washing Machine Tub: Complete Guide to Deep Clean & Eliminate Odors

The Hidden Problem Lurking in Your Laundry Room

Your clothes come out of the washer smelling musty instead of fresh. You notice black spots around the rubber gasket. That unpleasant odor hits you every time you open the lid. These aren’t just minor inconveniences – they’re signs of serious bacterial buildup that can affect your family’s health and damage your expensive appliance.

Ignoring washing machine tub maintenance can lead to costly repairs, ruined clothes, and potential health risks from mold exposure. The good news? This comprehensive guide reveals exactly how to clean the washing machine tub using proven methods that eliminate 99% of bacteria and extend your machine’s lifespan by years.

Why Your Washing Machine Tub Needs Regular Cleaning

Most homeowners assume their washing machine cleans itself with each load. Unfortunately, this couldn’t be further from the truth. Every wash cycle leaves behind microscopic residue from detergents, fabric softeners, and dirt that gradually builds up in hidden areas of your washer tub.

The warm, moist environment inside your washing machine creates the perfect breeding ground for bacteria, mold, and mildew. Studies show that washing machines can harbor over 60 different types of bacteria, including potentially harmful strains like E. coli and Staphylococcus.

Regular washing machine tub cleaning isn’t just about eliminating odors – it’s about:

• Preventing costly repair bills from clogged pumps and filters
• Ensuring your clothes actually get clean instead of recontaminated
• Protecting your family from harmful bacteria and allergens
• Maintaining your appliance warranty (many manufacturers require regular maintenance)

The Science Behind Washing Machine Odors & Biofilms

Here’s what most cleaning guides won’t tell you: the persistent smell in your washer isn’t just soap scum – it’s biofilm.

Biofilms are complex communities of microorganisms that form protective barriers, making them incredibly difficult to remove with standard cleaning methods. These microscopic colonies attach to every surface inside your washer tub, from the drum walls to the detergent dispenser.

Why biofilms are so problematic:

• They resist traditional cleaners and high temperatures
• They continuously release odor-causing compounds
• They can harbor pathogenic bacteria that contaminate your laundry
• They reduce the effectiveness of detergents over time

Research published in Applied and Environmental Microbiology found that biofilms in washing machines can survive temperatures up to 140°F – higher than most hot water cycles. This explains why simply running a hot water cycle doesn’t solve the odor problem.

The solution requires targeted cleaning agents that can penetrate and dissolve these protective biofilm barriers while eliminating the underlying bacterial colonies.

Essential Supplies for Tub Cleaning

Before starting your tub clean cycle, gather these essential supplies:

Natural Cleaning Arsenal:

• White vinegar (2 cups minimum)
• Baking soda (1 cup)
• Hot water access
• Microfiber cloths (lint-free)
• Old toothbrush for detail work
• Rubber gloves

Commercial Options:

• Affresh washing machine cleaning tablets
• Tide Washing Machine Cleaner
• OxiClean Washing Machine Cleaner
• Manufacturer-specific cleaners (like Samsung’s Eco Tub Clean tablets)

For Deep Cleaning:

• Enzymatic cleaners (for protein-based buildups)
• Chlorine bleach (for severe mold issues)
• Descaling solution (for hard water areas)

Pro Tip: Never mix chlorine bleach with vinegar or other acidic cleaners – this creates dangerous chlorine gas.

Step-by-Step Cleaning Methods

Method 1: Natural Vinegar & Baking Soda Deep Clean

This natural cleaner for washing machine tub method effectively breaks down biofilms and eliminates odors without harsh chemicals.

Step 1: Prepare the Machine

• Remove all clothes and check pockets for debris
• Clean the lint trap and detergent dispenser
• Ensure the drum is completely empty

Step 2: Add Cleaning Agents

• Pour 2 cups white vinegar into the detergent dispenser
• Add 1 cup baking soda directly into the drum
• Set your machine to the hottest, longest cycle available

Step 3: Run the Cleaning Cycle

• Start the hot water cleaning cycle
• Let it run for 5 minutes, then pause for 1 hour (allows cleaners to penetrate biofilms)
• Resume and complete the full cycle

Step 4: Detail Cleaning

• Wipe down all accessible surfaces with vinegar solution
• Clean the rubber gasket thoroughly, checking for trapped debris
• Remove and clean the detergent dispenser separately

Step 5: Final Rinse

• Run an additional rinse cycle with plain water
• Leave the door/lid open to air dry completely

Method 2: Commercial Cleaning Tablets

For busy households, using washing machine cleaning tablets offers a convenient, highly effective solution.

Popular Options:

• Affresh tablets: Designed to penetrate biofilms and remove mineral deposits
• Tide Washing Machine Cleaner: Specifically formulated for HE machines
• Brand-specific cleaners: Samsung’s Eco Tub Clean, LG’s Tub Clean tablets

Usage Instructions:

1. Place one tablet directly in the drum (not the dispenser)
2. Run the hottest cycle available or use your machine’s Self Clean mode
3. Wipe down surfaces after the cycle completes
4. Run an additional rinse if recommended by the manufacturer

Method 3: Heavy-Duty Mold Removal

For severe mold issues, this intensive deep clean washing machine method may be necessary:

Safety First: Ensure proper ventilation and wear protective equipment.

1. Initial Assessment: Identify all visible mold locations
2. Pre-treatment: Apply diluted bleach solution (1:10 ratio) to affected areas
3. Cleaning Cycle: Run hottest cycle with 1 cup chlorine bleach
4. Neutralization: Follow with vinegar cycle to neutralize bleach residue
5. Final Sanitization: Run plain water cycle to remove all cleaning residues

Machine-Specific Cleaning Instructions

Front Load Washer Tub Cleaning

Front-load machines require special attention due to their horizontal drum design and rubber door seals.

Unique Challenges:

• Water trapped in rubber gaskets promotes mold growth
• Detergent dispensers are more complex with multiple compartments
• Lower water levels can leave residue on drum walls

Specialized Steps:

1. Gasket Deep Clean: Pull back rubber seal and clean hidden areas where water pools
2. Dispenser Maintenance: Remove entire dispenser assembly for thorough cleaning
3. Drain Filter Service: Clean the front access filter monthly
4. Door Position: Always leave door slightly ajar after use for air circulation

Recommended Frequency: Every 2-3 weeks for front load washer tub cleaning

Top Load Washer Tub Cleaning

Top-load machines have different maintenance requirements:

Advantages:

• Better natural ventilation reduces mold growth
• Easier access for manual cleaning
• Simpler dispenser systems

Special Considerations:

1. Agitator Cleaning: Remove and clean agitator assembly if possible
2. Fabric Softener Dispenser: Clean the center column dispenser thoroughly
3. Lid Gasket: Wipe down lid seal and hinges regularly

Recommended Frequency: Monthly top load washer tub cleaning
