Didn't work as advertised.
Had road tar on my car and the video showed it coming off with little effort. If you have a very thin layer of tar, you'll be ok, but I had some spots that were just a bit thicker and although I saw residue on the rag, it would have taken me hours to remove. It does clean grease very well. I would still use it for my vehicle just to clean road grease splatter.
