I really like Arm & Hammer products. I had a coupon so decided to try Arm & Hammer Scrub Free Bathroom Cleaner with Oxy Foaming Action. It was ok but not at the top of my list. I think this is good for light jobs but not the super tough ones. Overall, if you have a lot of soap scum build up or tough stains I would try something else. Performance I think this would be better to use on a regular basis to prevent soap scum build up. I wouldn't try to use this to remove soap scum that is already fairly heavy. It is not scrub free. To be fair however, most products that say they're scrub free truly aren't to one degree or another. I like that this has Oxy in it because it's a good cleaning agent. I think this is good for light cleaning jobs but it doesn't have the same power as a scrub like Comet, Soft Scrub, or Tilex. Scent This doesn't have a terrible scent. It smells like most cleaners. It's not as toxic smelling as some bathroom cleansers. I didn't have to open all the windows to use it.
