The appear­ance of an unpleas­ant musty smell and black spots on the walls of the refrig­er­a­tor cham­ber is an indis­putable sign that mold has appeared in the refrig­er­a­tor.

The pres­ence of an unpleas­ant smell is the least prob­lem caused by the appear­ance of mold. First of all, it can quick­ly spread through­out the entire vol­ume of the refrig­er­at­ing cham­ber. Get­ting on prod­ucts, caus­es their infec­tion. It is a mis­take to assume that by cut­ting off a place affect­ed by mold, you can then eat the prod­ucts. Such foods — espe­cial­ly milk, rice and fish — should be dis­card­ed. After all, the ingress of mold spores into the human body can pro­voke the devel­op­ment of var­i­ous dis­eases.

The negative impact of mold

  • Mold spores are the strongest aller­gen, their entry into the lungs can cause the devel­op­ment of pharyn­gi­tis, rhini­tis, bron­chi­tis, and symp­toms of pneu­mo­nia. Mold often caus­es asth­ma.
  • If ingest­ed, mold can cause food aller­gies. Poi­son, accu­mu­lat­ing in the liv­er, can cause cir­rho­sis.
  • Mold spores begin to depress the immune sys­tem, a per­son becomes more sus­cep­ti­ble to var­i­ous dis­eases.
  • It can pro­voke the devel­op­ment of var­i­ous types of der­mati­tis and oth­er skin dis­eases.

Locations of mold

Cor­ners, var­i­ous recess­es and grooves will require spe­cial atten­tion dur­ing pro­cess­ing, but spe­cial efforts must be focused on two places:

  • Seal­ing rub­ber — con­den­sa­tion often accu­mu­lates here, which is a favor­able envi­ron­ment for the active devel­op­ment of mold. Do not treat it with bleach — it dries the rub­ber. After pro­cess­ing, the seal must be lubri­cat­ed with petro­le­um jel­ly.
  • In refrig­er­a­tors with auto-defrost (drip sys­tem), mold often appears in the drain hole, which serves to drain the result­ing con­den­sate on the back wall. To com­plete­ly remove the mold, it is nec­es­sary to addi­tion­al­ly pour a dis­in­fec­tant solu­tion into the drain (for this you can use a fun­nel or ene­ma), you can also clean it with a small brush. The cause of excess mois­ture in the refrig­er­a­tor (as a result, the appear­ance of fun­gus) often becomes a block­age in the drain, so con­den­sa­tion begins to accu­mu­late.

How to get rid: proven methods

There are many ways to get rid of mold in the refrig­er­a­tor. The most effec­tive is the use of spe­cial chem­i­cals. They are the most effec­tive, but after using them, you must thor­ough­ly wash the refrig­er­a­tor again, they can leave a pun­gent odor. Some house­wives are forced to aban­don their use due to aller­gic reac­tions. How­ev­er, you can remove the fun­gus with the help of cheap­er, but no less reli­able and proven folk reme­dies.


Before you start pro­cess­ing the inter­nal sur­faces of the refrig­er­a­tor com­part­ment, you must remove all prod­ucts, care­ful­ly inspect them and throw away every­thing that shows signs of mold!

It is nec­es­sary to get/remove all trays, shelves and draw­ers that need to be washed sep­a­rate­ly. For the time it takes to clean the refrig­er­a­tor, all remov­able parts should be soaked in water, adding two cups of vine­gar. After pro­cess­ing, they must be dried well.


Sodi­um bicar­bon­ate has excel­lent dis­in­fect­ing and cleans­ing prop­er­ties. The advan­tage of bak­ing soda is that it helps not only to remove the mold, but also helps to pre­vent its recur­rence in the future. To remove the fun­gus, we dilute the soda in water (1 table­spoon of soda for 1 liter of water) and care­ful­ly wipe all shelves and nich­es dry, pay­ing spe­cial atten­tion to hard-to-reach places. After pro­cess­ing, it is nec­es­sary to dry thor­ough­ly and ven­ti­late the refrig­er­a­tor. To enhance the effect, you can add a lit­tle vine­gar to the solu­tion.


Bak­ing soda, even when dis­solved, is a mild abra­sive. In addi­tion, it does not always dis­solve com­plete­ly, so do not rub hard with a sponge — you can scratch the sur­face of the cam­era.

Laundry soap and bleach

After lath­er­ing the sponge, wipe the refrig­er­a­tor, and then rinse off the soap suds with clean water.

Chlo­rine bleach removes black spots well, but leaves behind a very strong char­ac­ter­is­tic smell, so the cam­era will have to be washed well again and dried.

Hydrogen peroxide

Hydro­gen per­ox­ide has anti­fun­gal and dis­in­fec­tant prop­er­ties. Undi­lut­ed per­ox­ide is poured into a spray bot­tle, after which the entire sur­face is sprayed, pay­ing spe­cial atten­tion to the foci of infec­tion. Alter­na­tive­ly, you can use an ordi­nary sponge. After 2–3 min­utes, wipe every­thing with a clean cloth / nap­kin.


Hydro­gen per­ox­ide can bleach sur­faces, so it is not rec­om­mend­ed to use it in refrig­er­a­tors with a dark-coloured cool­ing cham­ber.

It is very impor­tant to dry the refrig­er­a­tor well after pro­cess­ing. To speed up the process and achieve a good result, you can use a fan heater or hair dry­er. To fix the effect and pre­vent the recur­rence of mold, the refrig­er­a­tor com­part­ment can be treat­ed with an ultra­vi­o­let lamp.

How to prepare the refrigerator for winter in the country

Quite often, mold appears in a refrig­er­a­tor or freez­er that has been in a long idle time — this is a char­ac­ter­is­tic “dis­ease” of freez­ing equip­ment that has win­tered in a gar­den house in the coun­try. In order not to waste time and effort in the spring fight­ing an unwant­ed “guest”, the refrig­er­a­tor needs to be cor­rect­ly pre­pared for a long break in work. First of all, it is nec­es­sary to thor­ough­ly clean and dis­in­fect the refrig­er­a­tor com­part­ment. In this case, you can use very strong means — dur­ing the win­ter the smell will have time to com­plete­ly dis­ap­pear. After wash­ing, the refrig­er­a­tor must be wiped dry. The door must be left open for the win­ter — this will cre­ate the min­i­mum accept­able con­di­tions for the occur­rence and devel­op­ment of mold inside the refrig­er­a­tor. Even if it man­i­fests itself before spring, it will not be dif­fi­cult to get rid of mold.

How to prevent mold from growing in the refrigerator

The opti­mal con­di­tions for mold devel­op­ment are mois­ture and stag­nant air. So to pre­vent its man­i­fes­ta­tion is quite sim­ple:

  • Inside the refrig­er­a­tor, it is nec­es­sary to place a sub­stance that will absorb / absorb excess mois­ture, mak­ing the air in the cham­ber dry. A proven method is to use spe­cial sil­i­ca gel or, if it is not at hand, impro­vised means, such as bak­ing soda or acti­vat­ed char­coal. The lat­ter is also sup­port­ed by the fact that in addi­tion to mois­ture, it also absorbs odors. Peri­od­i­cal­ly (opti­mal­ly — once a month) soda must be changed to fresh.
  • Reg­u­lar ven­ti­la­tion — just leave the refrig­er­a­tor door open for 0.5–1 minute, dur­ing which time almost com­plete air exchange will occur.
  • Remove spoiled food from the refrig­er­a­tor imme­di­ate­ly. A spoiled prod­uct not only becomes a breed­ing ground for the devel­op­ment of mold, but also a source of infec­tion for the entire refrig­er­a­tor.
  • Ensure the tight­ness of the refrig­er­at­ing cham­ber — seal­ing gum should fit snug­ly against the body, not let­ting warm air sat­u­rat­ed with water vapor inside.
  • It is advis­able to use spe­cial con­tain­ers for stor­ing food, with tight-fit­ting lids.
  • If some­thing is spilled and even just a lit­tle dripped onto the shelf, imme­di­ate­ly wipe it clean.
  • Do not start the sit­u­a­tion — at the first slight­est sign of the appear­ance of fun­gi or mold, imme­di­ate­ly thor­ough­ly wash the cam­era.

The appear­ance of an odor does not always mean that mold or fun­gus has set­tled in the refrig­er­a­tor. Heavy “smell” could result from mix­ing the aro­mas of dif­fer­ent prod­ucts. Indi­vid­u­al­ly, they smell very appe­tiz­ing, but their com­bi­na­tion can result in an annoy­ing, unpleas­ant stench. That is why prod­ucts with a strong odor must be stored in a her­met­i­cal­ly sealed con­tain­er, as an option — tight­ly packed in cling film.


Do not place fragrances/air fresh­en­ers in the refrig­er­a­tor com­part­ment. They do not absorb, but mask the smell of anoth­er, more intense one. This can cause the food to absorb the smell of the fresh­en­er and lose its nat­ur­al aro­ma and taste.

There is anoth­er effec­tive method on how to get rid of the smell of mold in the refrig­er­a­tor. To do this, sev­er­al slices of fresh lemon on a saucer should be placed in the cham­ber for sev­er­al days. If the smell con­tin­ues, you can try replac­ing the lemon.
