🦠 Source of Bacterial Growth! Removing Foreign Objects Inside the Washing Machine: Know-How for Cleaning the Tub, Lint Filter, and Rubber Gasket

Fiber debris, detergent residue, hair, and limescale that were not filtered out remain inside the washing machine, becoming a hotbed for bacteria and mold growth. Especially in the rubber gasket of humid drum washers or the lint filter of the tub, foreign objects can accumulate, causing bad odors and fabric contamination. We share the know-how for removing foreign objects and cleaning the inside of the washing machine to maintain cleanliness.

🔑 Core of Washing Machine Foreign Object Removal: Regular Cleaning, Mold Removal, Residual Water Management

The key is regular cleaning of unseen areas, mold removal, and residual water management where water tends to collect.

💡 3 Steps for Removing Foreign Objects Inside the Washing Machine

1. 🧼 Cleaning the Inside of the Tub (Tub Clean):

  • Use Tub Cleaner: Run the 'Tub Clean Cycle' or 'Boil Cycle' using a washer tub dedicated cleaner (oxygen bleach component) about once a month. (Lukewarm water at 40°C~60°C is effective.)
  • Utilize Baking Soda/Vinegar: Adding 1 cup of baking soda and 1/2 cup of vinegar to the tub and running the washer helps remove bacteria and mold.

2. 🦠 Managing the Drum Washer Rubber Gasket and Door:

  • Clean Rubber Gasket: Water and residue collect easily inside the rubber gasket around the drum washer door, allowing mold to grow. For moldy areas, apply a diluted bleach (chlorine bleach) solution soaked into a paper towel and leave it for about 1 hour before wiping. (Ventilation is essential when using bleach.)
  • Door Drying: Always leave the door open after washing to fully dry the interior and the rubber gasket.

3. 🧹 Managing the Lint Filter and Drain Hose:

  • Clean Lint Filter: Detach the lint filter (drain filter) located at the bottom or inside the tub and use a toothbrush to thoroughly remove fiber debris and limescale. (Be cautious of residual water flowing out when cleaning the filter.)
  • Clean Detergent Dispenser: Regularly detach and clean the dispenser where detergent and fabric softener residue may have hardened.

The cleanliness inside the washing machine is directly related to the cleanliness of the clothes. Periodic management of unseen areas is important.
