In a bowl, mix 50 ml of vodka, 50 ml of vinegar (6%), 100 ml of water and a teaspoon of tar soap or dishwashing liquid. Pour everything into a spray bottle.
For cleaning, you will need a stiff brush and a soft sponge.
Spray the mixture on the dirty areas. If necessary, you can add more detergent. Then wipe with the soft sponge. The detergent perfectly dissolves the grease, and the brush accelerates and optimizes the cleaning process.
