Dryer Sheets

I am trying to be more enviromentally conscious and waste less.  I really hated the waste of dryer sheets and there always is a bunch laying around from the laundry.  I googled reusing dryer sheets and a found a bunch of articles about how they work great for cleaning your tub of soap scum.  I started saving them and today I finally put them to use.  I was pleasantly surprised at how well they worked.  You still need to scrub but I could see the scum coming off.  I did find the sheets to be flimsy and I would need a bunch to do a really good job but they are effective and once I get my scum cleared, I think they will work brilliantly to keep the scum from building up.
