Black mold growing on the rubber seal of your refrigerator door (the gasket) is not only unsightly, but it also poses serious health risks. Luckily, with the right method and common household ingredients, you can remove it in just minutes—without damaging your appliance.
🧫 Why Does Black Mold Grow on Refrigerator Gaskets?
The rubber seal around your refrigerator door is prone to mold growth for several reasons:
- Moisture: Refrigerators produce condensation, especially in humid climates.
- Organic residue: Food spills or particles get trapped in the seal.
- Dark environment: Mold thrives in cool, dark, and damp spaces.
According to a 2012 study published in the Journal of Applied Microbiology, rubber seals in domestic appliances are among the most common breeding grounds for fungal spores in kitchens.
🚨 Health Risks of Black Mold
Black mold (Stachybotrys chartarum) and other common molds can trigger:
- Respiratory issues
- Allergies
- Skin irritations
- Asthma attacks in sensitive individuals
A 2004 WHO report confirmed the link between indoor mold exposure and increased risks of respiratory illness in both children and adults.
