As I told you before, it took us (my family) a full week of misery, when I was in the WWCofG, to scrub out the registers and detail strip the house and car to find that hidden sin. Lol
It created so many bad attitudes with the kids, we didn't have to look for hidden sin, it was there in front of us for everyone to see. Lol

I did quite a bit of research on it this year. That hypercleaining seems to be more rooted in Jewish tradition than anything else. The intent of course is good, to equate the physical action of cleaning out all the leaven with sin, but I think the intent of the commandment is that we don't ingest leavening. I don't think anyone is going to eat the little dust crumbs they find on the floor. :-).
What we do is to take all the food we find that has leavening and take it down to the Salvation Army kitchen and then we don't eat leavening for a week.
It's pretty easy this year since both my wife and I are on the atkins diet and have pretty much avoided bread for the last month or so.
