A couple years ago I (Conservative) was asked by my wife (Baptist) to educate her church by running a Seder for them. I cleaned the kitchen and serving areas as best I could, vacuumed the carpets, and moved the chametz off-site. Boiling was unrealistic, so my main cleaning agents for dishes and utensils were soap, hot water, and bleach.

Since bleach sterlizes, is that sufficent for rendering anything touching food fit for Passover?

    Short answer: no. Long answer: it might serve some useful purpose, but still no.

    If the Baptists were not Jewish why would they be concerned about the fitness of the food for Passover? Commented Nov 20, 2013 at 20:54

    Furthermore, boiling would be insufficient for many kitchen utensils such as the oven. For that, you'd better hope it has a self-cleaning cycle or get ready to pull out your handy blowtorch (or setting the temperature really high for a long time, but where's the fun in that?).

Star-K has an entire article dedicated to kashering for Pesach. Different types of utensils require different methods for kashering them. Bleach is not even mentioned in the article, so I think it's safe to assume that it doesn't do the trick.


Well... it seems that according to this answer, the Chazon Ish holds that it's ok to kasher using bleach, even l'chatchila.

    Re your edit: He was talking about performing hag'ala with a boiling bleach/water solution, not just scrubbing with bleach.
