Refrigerator is an irreplaceable assistant in the house – what else can keep the products fresh for a long time, not let the ice-cream melt, and freeze some ice for cold drinks when it’s hot? Only it – a tall snow-white good-looker, quietly murmuring in the corner of the kitchen. The fridge is designed for storage of foods, which means it shall always be clean. Of course, this cleanliness requires constant attention. Even the neatest housewife may have some expired products in the fridge. It may lead not only to an unpleasant odor, but also to the emergence of malignant bacteria in the fridge. Foods can soil the shelves, for example, when the package is broken. Therefore, it is important to revise the contents of the fridge regularly and clean its shelves. Especially since it is pretty easy to wash the fridge, you just have to remember a simple procedure.
Cleaning the fridge step by step
First of all, you have to disconnect the refrigerator from the mains and take out all the products. Expired foods and everything that got spoiled or moldy shall be disposed of. You will also have to get rid of all the unnecessary products, especially the ones long-forgotten in the deep-freeze compartment. Berries from your own garden, which have been frozen a year ago, unfortunately, lost this battle against the time, and you no longer have to cherish the hope that they might still be used.
If the fridge does not have the “No Frost” system, i.e. Frost is accumulated on the inner surface of the deep-freezer compartment, then you have to ensure the melt water drain (this shall be described in detail in the device user manual).
The next step: All shelves, boxes, containers and other detachable parts shall be removed from the fridge. This way, it will much easier to wash and dry them effectively, than trying to wash them diving deep into the fridge.
How to wash the shelves and the fridge interior surface and what to use for it? Shelves and boxes do not fit into the dishwasher, they shall be washed by hand. Especially since hot water is strictly forbidden for them – it can cause cracks on plastic and glass because of sudden changes in temperature. Therefore, the shelves shall only be washed by hand, as a rule, with the same agent as for the interior surface of the fridge. By the way, after washing, shelves, grills and boxes shall be dried well before placing them back.
The inner surface of the fridge also is contaminated quite often and requires cleaning: something might get spilt, some products leaked, an old piece of something left a smelly stain. The fridge door shall also be kept in mind, since it “suffers” probably most of all: we always open and close the fridge, put some products onto the door shelves, most often these are packs or bottles, the contents of which can be easily spilt. In addition, when washing the refrigerator interior, malignant bacteria and mold fungi, as well as excess moisture and dust are removed from the surface.  Thus, even if there are no visible contaminations on the inner surface, it still shall be washed thoroughly.
What to wash the refrigerator with?
There are lots of agents and methods for cleaning dirt off of the fridge. However, are all of them safe for the device itself and for humans? Our grannies and mothers used a solution of vinegar to wash the inner surfaces of the fridge. This method is effective, but, unfortunately, it does not guarantee that that no damage would be caused to the plastic parts and the door rubber. The same relates to ammonia solution. Moreover, both vinegar and ammonia have a specific smell which does not disappear and still remains inside the fridge, without mentioning the harmful effect of these liquids upon our bodies.
Baking soda is odorless, but it has obvious abrasive properties, so it can leave tiny scratches on the glass and plastic, which is impermissible.
Washing powders, dishwashing detergents or creams for stoves are definitely not suitable for cleaning the fridge. Such agents are difficult to wash out from hard-to-reach spots, have a specific odor or an explicit perfume. In the future, agent particles can get on the foods, which can be dangerous for health.
To restore cleanliness in the fridge, special agents shall be used. For example, UNICUM Refrigerator cleaner, which is suitable for plastic, glass and metal, is totally safe for all types of surfaces in the fridge, gently removes all kinds of dirt, prevents emergence of unpleasant odors and washes away instantly.
To remove stains and dirt in the fridge, it is better to use a soft cloth, sponge or a microfiber wipe. Sponges with abrasive surfaces, brushes, metal and plastic sponges leave scratches, where dirt, hazardous bacteria and mold accumulate, thus turning the fridge surfaces into a nidus.
When the cleaning is finished and all shelves, boxes and surfaces are dry, it’s time to put the food back into the fridge, remembering to check their quality once again, and turn the fridge on.
On average, the fridge shall be thoroughly cleaned every three months. Some lucky owners of “No Frost” refrigerators do such cleaning even rares, but it isn’t right. It is better not to let dirt accumulate, so as you wouldn’t have to lament about stubborn stains on the shelves in the future and an awful odor when opening the door.
