Suddenly detected yellow spots on the shelves or walls of the refrigerator can ruin the mood of any home cook. This is not only an aesthetic problem, but also a potential source of unpleasant odors that can permeate stored food. Most often, the reason lies in spilled tea, juice, the reaction of plastic with fat, or even the beginning of the oxidation process of materials.
Before grabbing aggressive chemicals, it is necessary to accurately determine the nature of the contamination. Plastic, from which internal parts are made, reacts differently to acidic and alkaline environments. An incorrectly selected product can make the situation worse, leaving irremovable stains or damaging the structure of the material. In this article we will analyze professional and folk methods of combating yellowness.
It is important to understand that old refrigerators can turn yellow due to the natural aging of plastic under the influence of ultraviolet radiation or temperature changes. However, in most cases we are talking about stubborn dirt that can be removed. The main thing is to act consistently and use time-tested recipes.
Causes of persistent yellowness
Understanding the source of the problem is half the success in the fight for cleanliness. Yellow spots may be the result of simple carelessness, when spilled soup or compote was not wiped up immediately. Over time, organic substances are absorbed into the micropores of the plastic, and ordinary water no longer absorbs them. Drinks with dyes and tea are especially aggressive in this regard.
Another common cause is contact of metal objects with a wet surface. If you placed jars with metal lids or pans with damaged enamel in the chamber, rustcould form on the bottom. It quickly penetrates the structure of the material and requires specific means for removal. Yellowness may also be a consequence of the development of mold in hard-to-reach corners.
Sometimes a color change occurs due to a chemical reaction of the material itself. Cheap, low-quality plastic can oxidize over time, especially if the refrigerator is located next to a window and is exposed to direct sunlight. In such cases, it can be extremely difficult to return the factory whiteness, but it is possible to lighten the surface.
⚠️ Attention: If the yellow spots are accompanied by a sticky coating and a strong smell of rot, the problem may lie in a malfunction of the condensate drainage system. Check the drainage hole.
Preparation for cleaning and safety measures
Before starting active operations, it is necessary to properly prepare the equipment. Any cleaning begins with a complete disconnections device from the mains. This is a basic safety rule that cannot be ignored, even if you only plan to wash the inner tube. Moisture and electricity are a dangerous combination.
After defrosting, remove all removable elements: shelves, drawers, egg trays. It is more convenient to wash them separately in a bathtub or large basin. For the main chamber, prepare soft sponges, microfiber and a spray bottle. The use of abrasive scrapers is strictly prohibited, as they will leave micro-scratches into which dirt will clog even faster.
Be sure to use rubber gloves. Even natural products such as vinegar or citric acid can cause skin irritation with prolonged contact. If you plan to use household chemicals, ensure good ventilation of the kitchen by opening a window or turning on the hood.
☑️ Preparing to clean the refrigerator
Folk remedies: soda, vinegar and lemon
The most affordable and safest way return the refrigerator to a neat appearance - use kitchen products. Baking soda works as a mild abrasive and an excellent adsorbent. To prepare the paste, mix baking soda with a small amount of water until the consistency of thick sour cream. Apply the mixture to the yellow areas and leave for 15-20 minutes.
Acetic acid does an excellent job of removing greasy plaque and mineral deposits. Mix 9% table vinegar with water in a 1:1 ratio. This solution can be sprayed onto the walls or wiped over the surface with a rag. Citric acid It acts similarly, but leaves a pleasant fresh aroma, interrupting the odors of the old refrigerator.
For complex stains, you can combine these products. For example, first apply soda slurry and then sprinkle it with vinegar. A foaming reaction will begin, which will help “pull” dirt out of the pores of the plastic. After the procedure, be sure to thoroughly rinse off the remaining products with clean water and wipe dry.
Removing rust and traces of dyes
If yellow spots have a reddish tint and appear in places contact with metal is most likely corrosion. Regular detergents may be useless here. An effective solution is to use weak acids or special rust removers. A mixture of lemon juice and salt has worked well.
Traces from dye packets, berry juices or spices (for example, turmeric) require a different approach. Whitening ingredients will help here. You can use toothpaste (not gel, but classic white) or shaving foam. Apply the product to the stain, lightly rub with a toothbrush and leave for a while.
In especially severe cases, when traditional methods are powerless, hydrogen peroxide comes to the rescue. It is a mild bleach. Soak a cotton pad in a 3% peroxide solution and apply to the stain for 10-15 minutes. To enhance the effect, you can cover the compress with cling film so that the product does not dry out.
| Type of contamination | Recommended product | Exposure time |
|---|---|---|
| Greasey coating | Vinegar or household solution soap | 10-15 minutes |
| Rust | Citric acid or special products | 20-30 minutes |
| Traces of berries/juices | Toothpaste or hydrogen peroxide | 15-20 minutes |
| Mold | Soda with vinegar or chlorine-containing products | 30 minutes |
Household chemistry: what to choose for plastic
When home recipes fail, you have to turn to industrial chemistry. Dishwashing detergents are suitable for cleaning the inside of refrigerators, as they break down grease well and are easily washed off. Acid-based plumbing cleaning gels can also be effective, but require very thorough rinsing.
There are specialized sprays for cleaning refrigerators. They are usually antibacterial and safe for food contact once dry. When choosing, pay attention to the label “for plastic” and the absence of chlorine, if the manufacturer does not recommend its use.
Melamine sponge is an “eraser” for dirt. She works wonders with yellow stripes on doors and handles. It works due to the microabrasive structure of the fibers. Simply dampen the sponge with water and lightly rub the problem area. Do not press hard, otherwise you may damage the glossy finish.
⚠️ Attention: Never use acetone, solvents or products with aggressive abrasive particles. They can melt the plastic or leave permanent scratches.
Can I use bleach (White)?
You can use chlorine-containing products, but with great caution. They are great at removing mold and bleaching, but can damage the rubber seals, making them hard. After treating with bleach, the refrigerator must be ventilated very thoroughly.
Cleaning seals and hard-to-reach places
The rubber seal around the perimeter of the door is a magnet for dust, crumbs and mold. It is in the folds of rubber that sources of yellowness and unpleasant odor are often hidden. You need to clean it carefully so as not to damage the elasticity of the material.
Use cotton swabs soaked in soapy water or vinegar. Go around all the curves, removing dirt from the grooves. If black mold has settled on the rubber, you can use a toothbrush with baking soda. Movements should be along the fold, and not across, so as not to stretch the rubber.
After cleaning, the rubber parts can be treated with glycerin or a special silicone lubricant. This will restore their shine, elasticity and protect them from drying out and cracking. Dry rubber loses its sealing properties, which leads to the formation of ice.
Prevention and care of equipment
So that the question “how to wash it” yellow spots" did not get up too often, it is important to follow the operating instructions. Any spilled liquids must be cleaned up immediately. Don't wait for the juice to dry out and turn into a sticky crust. Have a wet wipe on hand for quick cleanup.
Store food in closed containers. Opened packets of sauces, jars of jam or pieces of meat are best placed on saucers or deep plates. This will protect the shelves not only from leakage, but also from condensation that may drip from the lids.
Regularly, at least once a quarter, carry out general cleaning with defrosting. Even if there is no visible contamination, preventive treatment with a weak solution of vinegar or soda will help maintain hygienic cleanliness and freshness. This is especially true before storing seasonal items.
How often should you wash the inside of the refrigerator?
The optimal frequency of general cleaning is once every 3-4 months. However, if stains or an unpleasant odor are detected, cleaning should be carried out immediately, without waiting for the scheduled date.
Why does new plastic turn yellow?
New plastic may turn yellow due to a reaction with aggressive substances (for example, citrus essential oils) or due to direct exposure to sunlight. Also, the reason may be poor-quality shelf material.
Is it possible to wash a refrigerator with a steam generator?
You can use a steam generator, but with caution. High temperatures can warp some types of plastic. Direct the steam jet briefly and immediately wipe away the moisture.
How to remove the smell after cleaning?
It is best to ventilate the refrigerator with the door open for several hours. You can also place a bowl with activated carbon, ground coffee or a special odor absorber inside.
