Your LG washer works hard to keep your clothes fresh and clean, but when was the last time you cleaned the washer itself? Over time, detergent residue, lint, dirt, and moisture can build up inside the drum. This not only causes unpleasant odors but can also shorten your washer’s lifespan and lead to costly repairs.
The solution? LG’s Tub Clean cycle.
This built-in feature is designed to keep your washer hygienic, odor-free, and running smoothly. In this detailed guide, we’ll cover:
- Why the Tub Clean cycle is important
- Step-by-step LG Tub Clean cycle instructions
- Best cleaning agents to use (bleach, vinegar, or LG tablets)
- How often U.S. homeowners should run Tub Clean
- Tips to prevent mold and mildew buildup
- Troubleshooting if Tub Clean doesn’t work properly
Why Use the Tub Clean Cycle in Your LG Washer?
Many homeowners in the U.S. are surprised when their washer starts smelling bad or clothes come out less fresh. The reason is simple:
- Detergent residue builds up inside the drum and hoses.
- Moisture and heat create the perfect environment for mold and mildew.
- Fabric softener residue leaves a sticky coating that traps bacteria.
If ignored, this can lead to:
- Moldy gaskets and bad odors
- Drain pump clogs
- Increased risk of mechanical failure
- Shorter washer lifespan
👉 Running the Tub Clean cycle monthly prevents these issues and keeps your washer in peak condition.
LG Washer Tub Clean Cycle Instructions (Step-by-Step)
Here’s how to properly run the Tub Clean cycle in 2025 for both front-load and top-load LG washers:
For Front-Load LG Washers
- Empty the Drum
Remove all clothes, laundry, and items from the washer. Tub Clean must always be run with an empty drum. - Choose a Cleaning Agent
- LG Tub Clean tablet (recommended) – Designed for LG washers.
- Liquid bleach – Use 1 cup in the detergent dispenser.
- White vinegar – Add 2 cups directly into the drum for a natural alternative.
- Start the Tub Clean Cycle
- Close the washer door.
- Press the Tub Clean button on your LG control panel.
- If your model doesn’t have a Tub Clean button, select the Sanitary/Hot Wash cycle with no clothes inside.
- Wait for Completion
The Tub Clean cycle usually runs for 60–90 minutes at high temperature to kill bacteria and remove buildup. - Wipe the Drum & Gasket
Once finished, use a microfiber cloth to wipe the drum, door glass, and especially the rubber gasket (a common mold spot).
For Top-Load LG Washers
- Empty the Drum
Ensure no clothes are inside. - Add Cleaning Solution
- Add 1 cup bleach or LG Tub Clean powder/tablet directly into the drum.
- Avoid pouring vinegar into the bleach dispenser (to prevent damage).
- Run Tub Clean
- Select Tub Clean from the cycle options.
- If your model doesn’t have Tub Clean, run the hottest wash cycle without laundry.
- Air Dry the Drum
Leave the washer lid open to let the drum dry completely.
How Often Should You Run Tub Clean?
In the U.S., usage frequency matters.
- Light use (1–2 loads/week): Run Tub Clean every 3 months.
- Moderate use (3–5 loads/week): Run Tub Clean monthly.
- Heavy use (daily or large families): Run Tub Clean every 2–3 weeks.
👉 LG officially recommends running Tub Clean once per month for optimal performance.
