Thank you for the vid, I've found nearly anything pretty much does with cleaning chrome,The best thing I've used to clean chrome that's pretty crudded up, is 00 wire wool, you would think it would scratch, it doesn't as it's so soft, but it's amazing, add water for stubborn. I have problems getting water marks out of un polished alloy wheels, but same wool and elbow grease does it, then just pledge which I find great for repelling brake dust. But burn marks on exhaust, the wire wool as well, you will be impressed, Screwfix sell it.
