      Until the mixture starts to boil. Then shut off and leave door closed so that steam will accumulate inside.

      Put in microwave until it boils. Turn off microwave but leave the vinegar and water in microwave for 5 minutes. After 5 minutes you start wiping the inside until clean.

    Hi!! Please don't think I'm being critical!! I learned the hard way! Heating vinegar in a microwave releases dangerous fumes. The easiest way to do this is boil the water first then add room temper vinegar to the sponge to clean & disinfect

      Exactly what kind of Dangerous fumes are you referring to, from boiling vinegar water in microwave? Are you perhaps referring to chlorine and Fluoride in water? I am glad you mentioned the dangerous fumes that most people would not consider. You are right to boil water to evaporate the chlorine & fluoride out of water. I boil water daily to remove these toxins from my water then, refrigerate for uses throughout the day and week.

      Thank You for your Awareness to protect others- this is a life saver for many- Blessings unto you!

      Vinegar is 5% acetic acid boiling it will dissociate it simply The equation for the dissociation of acetic acid, for example, is CH3CO2H + H2O ⇄ CH3CO2− + H3O+. so no gas fumes of acetate ion are vinegary smell not dangerous at all!!

    Hi there. Really needed this tip so a big, 'thank you'. However, I am just wondering about someone's comment regarding dangerous fumes coming from the vinegar. Is this true?

    I wipe my microwave out EVERYDAY.......not OCD, just easier for me, as I wipe the stove top and vent all off. Thanks anyway!

    I just put a wet sponge in the microwave for a minute. Then use the sponge to clean the microwave. Have to wear heat gloves because the sponge is HOT.
