Before you start cleaning, you need to understand the source of the problem. In 80% of cases, an unpleasant odor occurs not because of poor cleaning, but because of:

• 🧀 Spoiled food - even a small piece of cheese or sausage, forgotten on the back shelf, can permeate the entire refrigerator with the aroma.
• 💧 A dirty drainage hole - grease, food particles and mold accumulate there, which emit a rotten smell.
• 🧽 Mold on the sealing rubber —its pores absorb moisture and become a breeding ground for bacteria.
• 🔥 Improper defrosting — if the refrigerator is thawed at room temperature, odors are “baked” into the plastic.
• 🧪 Chemical reactions for example, fish + onions or dairy products + citrus fruits create persistent "cocktails".

Many housewives make the mistake of simply wiping the shelves with a damp cloth. This removes visible dirt, but does not remove bacteria and microparticles that continue to emit odor. For example, up to 30% of all refrigerator microbes can be hidden in the seal Samsung RB37 or LG GA-B489 and regular washing does not reach them.
