I just clean mine whenever I think about it. It doesn't affect beam quality too much to have a little lint on there.
Your Arc will only sit there and laugh at your washing machine. I prefer a little warm water and a toothpick for more controlled cleaning.
Me too. I must admit that I had accidentally washed my Arc AAA P two times and my newer DS 1X. When you use a really small flashlight as a backup EDC there is always that risk. I would rather have this happen accidentally ever so often, than not take the light with me daily.

Why not just give up and have it happen on purpose, instead?
