The microwave is one of the most used appliances in the house and undoubtedly one of the most messy, especially on the internal walls of the microwave can accumulate dirt because of some splashes when heated.
A very easy and effective way to clean it is to introduce a bowl with water and 2 tablespoons of white vinegar in the microwave, start it for 3 or 5 minutes to get the water to evaporate and the steam that will come off undo the dirt incrusted on the walls of the microwave and, therefore, clean more easily. Then remove the bowl with some mittens or kitchen cloth. Clean the internal walls with a sponge and finally use a dry cloth and the microwave will be perfectly clean and free of bad odors.
