Sounds like those "Scrubs" are sort of "Wet Wipes" on steroids. I was watching pretty closely yesterday as I was using the WWs and I do think there is soap or cleaner that emerges as you are rubbing. I thought they were just saturated with alcohol - but now I'm convinced there is actually a cleaning agent. The Scrubs look like bigger, stronger WWs with a heavy duty cleaner.
Now the Consumer Reports Dept. of HR.Com needs to run side-by-side tests of the two products to see which one gets our "Best Buy" award.
