I'm not so traditional. Plus, I share my home with a non-Jew, so I think that simply refraining from eating bread and the like is enough. It is simply not practical to banish non-Passover foods from my kitchen.
But, inspired by a haggadah I read this weekend, I'm still cleaning out chametz. In my case, it's all the extra stuff that I don't need, the stuff that I don't want, and the clutter that makes my life less enjoyable. I spent a couple hours each of Saturday and Sunday, and since it's a 3-day weekend for me, today's the day for some heavy lifting. My focus has been on my bedroom, and it already looks much better. I'm getting excited to see my chametz-free room.
