Dutch Pimp Reviewed by Dutch Pimp on . gotta try this cleaning stuff! had the worst grimy stuff on my pipes. tried everything and couldn't get it back to the way it looked when I bought it but my friend gave me this stuff to try and all I had to do was pour it inside my big pipe and let it sit then rinse it. It's called OG Off Glass. best stuff ever and I usually don't recommend anything but this stuff is amazing. I'm a happy happy girl. :rasta: Rating: 5
