As microwave became a daily use item, is natural for it to bear the traces of all related activity. Sauces, pasta, pizza, sandwiches and many others, leave behind their specific odors and splashes which make the inner part of the microwave difficult to clean if not cleaned after every use. In order to escape the unpleasant smell and unclean look you don’t need other but a mug filled with water and a few drops of vinegar. Insert the mug into the microwave and set the timer for 5 minutes. When time is up, let the steam work with closed door for another 5 minutes, then open. Carefully remove mug and wipe clean with a damp cloth. Remove plate and wash separately.
