Introduction
Your washing machine works hard to keep your clothes fresh and clean, but one component that often gets ignored is the detergent tray. Over time, detergent residue, fabric softener buildup, hard water deposits and moisture create the perfect environment for mold, mildew and bacteria.
A dirty detergent tray not only causes unpleasant odors but also affects detergent distribution and washing performance. The good news is that you can easily perform a DIY Detergent Tray Deep Clean at home using simple household items.
In this complete guide, you'll learn how to clean a detergent drawer, why regular maintenance matters, common mistakes to avoid and when it's time to call professionals like Sajilo Sewa for washing machine servicing.
What Is a Detergent Tray?
A detergent tray (also called a detergent drawer or dispenser) is the compartment where detergent, fabric softener and pre-wash liquid are added before starting a wash cycle.
It automatically releases the appropriate cleaning solution during different stages of the wash cycle, ensuring clothes are cleaned effectively.
Without proper maintenance, detergent residue accumulates inside the tray and internal channels, reducing its efficiency.
Why Is Detergent Tray Cleaning Important?
Regular Detergent Tray Cleaning improves both hygiene and washing machine performance.
Prevents Mold and Mildew
Constant moisture inside the detergent drawer creates an ideal environment for black mold and mildew growth.
Benefits
Prevents black spots
Reduces bacteria buildup
Improves laundry hygiene
Eliminates unpleasant odors
Improves Washing Performance
When detergent residue blocks the dispenser, detergent may not dissolve properly.
Benefits
Better detergent distribution
Cleaner clothes
Better stain removal
Reduced detergent waste
Extends Washing Machine Lifespan
A clean detergent drawer prevents residue from entering internal components and causing unnecessary wear.

DIY Detergent Tray Deep Clean: Step-by-Step Guide
Step 1 – Remove the Detergent Tray
Most front-load washing machines have a release button inside the drawer.
Gently press the release mechanism and pull the tray completely out.
Step 2 – Rinse with Warm Water
Rinse the tray under running warm water to remove loose detergent and fabric softener residue.
Avoid using boiling water on plastic trays.
Step 3 – Soak the Tray
Prepare a solution using:
Warm water
White vinegar
Mild dish soap
Soak the tray for 20–30 minutes to loosen hardened residue.
Step 4 – Scrub Thoroughly
Use:
Soft brush
Old toothbrush
Microfiber cloth
Pay special attention to:
Corners
Detergent compartments
Water holes
Hidden grooves
Step 5 – Remove Mold
If mold is present:
Apply vinegar directly
Let it sit for 10 minutes
Scrub gently
Avoid mixing vinegar with bleach.
Step 6 – Clean Inside the Drawer Housing
Many people clean only the tray and forget the dispenser cavity.
Use:
Damp cloth
Soft brush
Cotton swabs
Remove detergent residue from inside the machine.
Step 7 – Dry Completely
Allow both the tray and housing to dry before reinstalling.
Proper drying helps prevent future mold growth.

Mistakes to Avoid During DIY Detergent Tray Deep Clean
Using Sharp Objects
Metal tools can scratch plastic surfaces and create spaces for bacteria accumulation.
Using Excess Bleach
Strong chemicals may damage plastic components and rubber seals.
Forgetting Internal Compartments
Cleaning only the removable tray leaves hidden mold inside the dispenser housing.
Not Drying the Tray
Leaving moisture behind encourages mold to return quickly.
Washing Machine Maintenance Tips
Proper Washing Machine Maintenance goes beyond detergent tray cleaning.
Leave the Door Open
After every wash, leave the machine door slightly open to improve ventilation.
Wipe Rubber Gaskets
Front-load washing machines collect moisture around door seals.
Regular wiping prevents mold buildup.
Run a Monthly Drum Clean Cycle
Use a washing machine cleaner or hot water cycle once every month.
Use the Correct Amount of Detergent
Too much detergent creates unnecessary residue.
Always follow manufacturer recommendations.
Clean the Filter Regularly
A blocked filter reduces drainage efficiency and causes unpleasant smells.
When DIY Cleaning Isn't Enough
Professional servicing is recommended if:
Mold keeps returning
Water doesn't enter the detergent drawer properly
Detergent remains after every wash
The machine produces bad odors despite cleaning
Internal dispenser pipes are blocked
These problems may require partial disassembly and professional inspection.
