What to wash the inside of the refrigerator to make it clean and fresh: 10 proven ways

The refrigerator is the only household appliance that works around the clock, keeping food fresh. But even with regular care, bacteria and greasy stains accumulate on its walls, and mold may appear in the corners. An unpleasant smell, sticky residue on the shelves and yellowness on the door seal are signals that it’s time to do some general cleaning. However, not all products are suitable for washing internal surfaces: aggressive chemicals can damage the plastic, leave a persistent chemical odor, or even penetrate into the products.

In this article we will look at 10 safe and effective ways washing the inside of the refrigerator, including folk recipes (soda, vinegar, lemon) and professional chemistry (sprays, gels, wipes). You'll learn how to remove stubborn stains without streaks, disinfect cameras, and prevent mold. And also - why you can’t wash the refrigerator with hot water and how to properly dry it after cleaning to avoid corrosion of metal parts.

Why the refrigerator needs to be washed regularly: 3 reasons

Many housewives clean the refrigerator only when it starts to “smell” or before general cleaning. But this is a mistake: hidden contamination can affect not only food freshness, but also health.

Here are three good reasons to wash the refrigerator at least once every 1-2 months:

• 🦠 Bacterial proliferation. Research shows that there may be more in the refrigerator 10 times more germsthan on the toilet seat. Particularly dangerous are Salmonella, E. coli and Listeria, which cause food poisoning. They accumulate on shelves, in egg trays and on sealing gum.
• 🧪 Mold and fungi. Moist environments and food debris create ideal conditions for black mold (Aspergillus), which can provoke allergies and breathing problems. Most often it appears in the drainage hole and on the back wall.
• 👃 Odor absorption. Plastic and rubber parts absorb the aromas of fish, cheese, and onions over time. If you do not remove them on time, the smell will become chronic, and it will be more difficult to get rid of it.

In addition, a dirty refrigerator consumes more electricity. Plaque on the ventilation grilles and rear wall impairs heat transfer, causing the compressor to work harder. According to Roskachestvo, this can increase electricity consumption by 10-15%.

Common mistakes when washing the refrigerator

Even experienced housewives sometimes make mistakes that can lead to equipment breakdown or deterioration in its performance. data-i="335">and how to avoid them: TOP-7 misconceptions and how to avoid them:

• 🚫 Use abrasive sponges. They scratch the plastic, and bacteria accumulate in microcracks. Use soft rags or microfiber.
• 🚫 Washing the refrigerator when it is on. This is life-threatening (risk of electric shock) and can damage electronic components.
