Yes it works
Ignore the reviewer that says they can't recommend this because it's 3%, how ridiculous. It says it right on the bottle. If it works, that is what your review should be about and you can always add the cost factor in. This did a great job of  cleaning my mat in the doorway. I also spray it on in my shower to help with discoloration. This isn't the best peroxide cleaner I've used but it's definitely not the worst and still better than most as it doesn't have that toxic smell. I like the gallon jug so I can pour it in my spray bottles and save some money. This is a solid product.
