Firstly, to remove mold and grime from the sealing rubber, a boric acid solution can be effective. To prepare it, dissolve 10 grams of the substance in 1/2 liter of water. Heat the mixture until the sediment is completely dissolved, then let it cool.
Next, soak a sponge, cloth napkin, or cotton pad in the solution and clean the contaminants on the sealing rubber and inside the drum. Wipe everything dry and apply the boric acid solution again.
Secondly, to eliminate dirt and unpleasant odors from the washing machine's seal, monarda extract can be helpful. For this, dilute 15 ml of the extract in 1 cup of distilled water. Pour the resulting mixture into a spray bottle and apply it to the stains. There’s no need to rinse it off. The specific smell of the solution will dissipate quickly.
Thirdly, to keep the washing machine clean for a long time, mix 2 drops of tea tree essential oil and 2 drops of lemon essential oil in 5 liters of water. Add a little baby shampoo or neutral liquid soap. Stir everything well and pour it into the fabric softener compartment. Start the wash cycle.
