Interesting experience, I didn't even know this existed. Honestly when I read the thread title, I thought somebody wanted to switch pads, and they were trying to gather users to see who needed what, and who could provide that for $$ or swap pads. :P
I still think my idea is a good idea.
Anyways, I only clean mine myself. It's a big job, but the peace of mind is worth it, let alone the fact that they're completely clean an I can be sure of it.
I'm sure they do great, but it's all about the personal touch, doing it yourself.
