The best way to clean a refrigerator: 7 proven methods and 5 mistakes that spoil equipment

The refrigerator is the only household appliance that works 24/7, accumulating inside not only food, but also bacteria, mold, and greasy food stains. Improper cleaning can not only leave streaks, but also damage the sealsdamage the coating or even damage electronic modules. In this article - the only complete guide to choosing detergents, taking into account the type of refrigerator (No Frost, drip, inverter), shelf material (glass, plastic) and degree of contamination.

We tested 12 popular products (from soda to professional chemicals), interviewed 5 refrigerator repair specialists and studied the instructions for the models Samsung RB37A5200, LG GA-B459SLGL, ATLANT XM 4021-000.

4. Cleaning the outside of the refrigerator: nuances for different coatings

External care is no less important: dust on the condenser (rear wall) increases energy consumption by 15-20%, and dirt on the handle is a breeding ground for bacteria. Cleaning methods depend on the material:

• 🔄 Stainless steel (For example, Liebherr CBPesf 4056>): use special polishes (Weiman Stainless Steel Cleaner) or vinegar solution (1:3 with water) Wipe along the metal fibers to avoid streaks.
• 🖼️ Plastic (most budget models): a soap solution is enough (72% laundry soap). For glossy panels (Samsung RT22HAR4DSA>), use a microfiber cloth.
• 🧲 Magnetic surfaces (for example, door Indesit DF 5200 S>): avoid abrasives - they erase the magnetic layer. An alcohol solution (1:1 with water) is suitable.
• 🔌 Displays and touch panels: use wipes for electronics (Kleenex Electronic Wipes>) or a solution of isopropyl alcohol 70%.

The frequency of cleaning depends on the intensity of use, but there are universal recommendations:

Type of cleaning	Frequency	What to do
Daily	1 time per day	Wipe the shelves with a damp cloth, remove spilled liquids
Current	1 time per week	Wash the shelves and boxes with soda solution, clean the seal
Deep	once every 3 months	Full defrosting (for drip models), drainage cleaning, disinfection
Emergency	As necessary	For leaks of meat/fish - disinfection with vinegar or Topperr 3101

For families with children or allergy sufferers, the schedule is adjusted: deep cleaning is carried out every 1-1.5 months, and for disinfection use Mellerud Bio for refrigerators (hypoallergenic product).

6. Features of cleaning No Frost refrigerators and drip systems

Defrosting technology dictates the nuances of care. Errors here lead to icing of the evaporator or fan breakdown.

No Frost (all models Samsung, LG, Bosch from 2018)

• 🚫 No scrape the ice with a knife or metal blades - this damages the evaporator.
• ❄️ Defrosting: just turn off the refrigerator for 12-24 hours. The ice will thaw itself (the fan will speed up the process).
• 🧼 To clean the ventilation holes, use cotton swabs soaked in alcohol.

Drip system (most ATLANT, Indesit, Gorenje)

• 💧 Defrost when the ice thickness is > 5 mm. Use a plastic scraper and a tray to collect water.
• 🔧 Clean the drainage hole every 6 months (clogged drainage is the main cause of puddles under the refrigerator).
• 🧽 After defrosting rinse the back wall with a vinegar solution (1:3) to remove limescale.

For inverter compressors (for example, Hitachi R-BG410P6M) it is important to avoid sudden temperature changes when cleaning. Do not turn on the refrigerator immediately after washing - wait until all parts warm up to room temperature (at least 1). hour).
