    you seem to have overlooked

    A small point. In this order the author mentions and highlights the importance of cleaning the showers of food from the walls, etc… Yet, the method supposedly being used to kasher the oven is steam and I quote: ” Just as the non-kosher food contaminated the microwave through its steam, the microwave can be kashered by filling the chamber with steam. The microwave must be clean of all food spills and splatters.” Yet those areas which had food splatters, would seem to need a koshering with hot water, not just steam. And in the lifetime of a microwave, food splatter… Read more »

    what I was told to do

    I was told to put my food in two ziploc bags and warm up like that. When the outer bag looks like it is going to pop, I stop the microwave, let out the air and close it up again and heat it up more if needed. I work in a very large office building and since they will not let me have my own microwave and it is not possible to kashur one everyday, this is what I was told to to.

    no styrofoam

    The article says to use a styrofoam cup. Do not put Styrofoam in the microwave for more than a minute, it will melt.

    … I would just stick with cold food rather than try to kasher a microwave that has obviously been used for treifes.

    I have two microwaves in my house (milchig & fleishig) and it is pretty much impossible to get the interior surfaces completely clean, especially at the seams and in the vents. Since I have many demands on my time, I’ve given up trying to get them perfectly clean. I don’t use them for Pesach anyway, so it really doesn’t matter if somewhere a pinpoint-sized piece of something is stuck.

    My $0.02.

    Do not put strofoam plastic with your food in microwave oven
    The chemicals from the plastic or the styrofoam will leach in to your foods,and might be a cause of many illnesses,may we be protected from.
    Always use only glass ,ceramic of paper

    Styrofoam

    Styrofoam is made with tallow (a form of beef fat). When heated, the meat by-product is released. It is unlikely that the beef used in Styrofoam is Lubavitch Shchita!

    practical point

    practical point

    Experience taught me that it is hard to steam up the microwave
    because the fan vents the vapors out.
    To overcome that I first bring the water to a boil, then shut the
    microwave with the cups inside for a while.
    That steams up the inside.!!

    The earlier Lubavitcher Rabbonim insisted on eeruy to kasher them, stating that there is no halachic president for
    kashering with steam. Who changed that , and on what basis?

    It is not true. The cup will not melt.

    Double wrap with MIcrowave

    Double wrap with MIcrowave

    I would assume that it is not possible to completely double wrap food in a microwave. The issue is that the package could explode if it is sealed. The vapors in wrapped food have nowhere to escape.

    #7: not tallow, but OH BOY!

    #7: not tallow, but OH BOY!

    The search engines list the composition of styrofoam as polystyrene, benzene and/or pine tree resin. if #7 has a source for tallow being included, could he please let us know. The fact that styro is made from up to 3 ingredients that may cause various illnesses sure does not make me happy. I’vebeen avoiding it for years,especially for hot things. The scary news, mentioned in a star-k article THE STORY BEHIND KOSHER PLASTICS, is not only that many ingredients in plastic materials can migrate into food, but that manufacturers a presently testing ways of making plastics like that on purpose,… Read more »
