i believe charlie said that they get rid of all their chametz so there is nothing left to sell
It really hasn’t been a burden to eat it all up, or give it to a non-Jew.
And if there’s a crumb somewhere in the house he didn’t know about? (And I know a lot of people who have found stuff larger than a crumb.) Then he owned chametz on Pesach. And the chametz that is absorbed in his keilim? Or does he kasher everything that can be and break what can’t be?
To charliehall: Have you asked a rav about this policy of yours?
