I Opticoated my (Spectra Gray) wheels and use Optimum car wash with a mitt dedicated to the wheels. Works great and takes maybe 4-5 minutes per wheel. I've used Rejex on wheels in the past with similar results. Brake dust cleans right off with either product.
Opti-seal when the wheels are clean and dry every couple of months. Sonex wheel cleaner/ rinse well then followed followed by microfiber wheel cleaning tool. Purchased from Autogeek
