Shower Cleaner on My Body?

So last night in the shower, I was thinking...this shower already needs to be cleaned again. I'm pretty sure I cleaned it LAST week. I shower once a day and Brent sometimes two. We have a pretty good size shower and it is made of fiberglass I believe. I remember seeing a commercial for an automatic cleaner and I vaguely remember thinking I heard someone say they use it...and like it! I am all about using an automatic toilet cleaner. You just drop that thing in the back or put a round thing up on the side. So anyways, I'm thinking, if you hang that automatic cleaner around the shower head, how does the shower cleaner not get on your body? How does it not get on your soap, razors, comb (in my case), etc....I thought I would do some research. The site is quite lengthy! Maybe when I have more time I'll look over it!

Have any of you used this? What did you think? If not, what do you think works best on fiberglass?
