Although it looks fine on the outside, the inside of the washing drum is a completely different environment. This is because moisture and detergent residue left over from the washing process accumulate repeatedly, creating a structure that is conducive to the breeding of bacteria and mold. In fact, if black residue floats up from the washing machine or if laundry has a musty smell, it is highly likely that internal contamination has progressed significantly. Although it is an appliance used daily, it is often neglected in terms of maintenance, making it a blind spot that requires attention.
It Looks Fine on the Outside, but the Inside is ‘Damp Everywhere’
The structure of the washing drum makes it difficult for the interior to dry completely. Even after washing, moisture remains between the walls and the rubber packing folds, sticking along with detergent residue. This damp environment is optimal for bacteria to multiply rapidly. In particular, front-loading washing machines tend to concentrate contamination inside the rubber packing, so even if they look clean on the outside, the internal condition can be entirely different. During high humidity periods like the rainy season or summer, the rate of contamination increases even more.
Various Cleaning Methods: Sodium Percarbonate, Vinegar, and Specialized Cleaners
The common principle that home management experts adhere to is ‘regular cleaning.’ Running the washing drum with sodium percarbonate at a high temperature of 50-60 degrees is effective for removing water stains and detergent residue. However, some washing machines do not recommend excessive high-temperature washing or the use of sodium percarbonate, so it is necessary to check the manual. Commercially available washing drum cleaners can manage both bacteria and mold in a single cycle.
Additionally, running an empty wash with vinegar can help alleviate odors and remove water stains inside the washing drum. However, since vinegar has limited sterilizing effects, it is appropriate to use it as a supplementary measure. It is safer to use sodium percarbonate and vinegar on alternate days rather than mixing them together. A cleaning cycle once a month is generally recommended as a basic practice.
Keeping the Door Open: The Easiest Preventive Measure
The habit of closing the door immediately after washing traps moisture inside. The basic management method is to open the washing machine door and detergent dispenser after use to allow the interior to dry thoroughly. Even a short period of ventilation can significantly reduce the amount of residual moisture. This simple habit can noticeably slow down the rate of mold growth, making it as important as cleaning.
Detergent Dispenser and Rubber Packing Also Need Management
If you only clean the washing drum and neglect the detergent dispenser or rubber packing, contamination will quickly recur. The detergent dispenser is prone to pooling water and detergent, leading to rapid bacterial growth. If it has a removable structure, it is advisable to take it out regularly, wash it, and dry it completely. Similarly, removing moisture from the inside of the rubber packing with a dry towel or soft brush can significantly reduce mold growth. Managing these small areas is crucial for the cleanliness of the washing machine.
