I just spray it on and let it sit for 10-30 seconds depending on how dirty it is and just wipe it clean. I will let the photos do the rest of the talking.
Funny, you posted this, I tried it today for the first time. My results were not as good as yours, but not the products fault, I had more pits from salt and painted rims. I was happy with would it did do!
yeah my little sparco emblem/logo didn't shine back up but I didn't have to scrub like I thought I would of had to. First 'real' clean they have had since I got them almost a year ago.
Thanks for the heads up. I used these on my Jeep wheels I have on my Eagle that are probably over 20 years old. I've tried other products like Simple Green and they still looked like crap. I wish I would have taken before and after pics, they look great now. I did have to scrub it just a little with a soft cloth.
