I bought some stuff from summit racing store. It is called Chemical Guys meticulous matte auto wash cleans matte and satin. Which I have both only about 10 bucks and a capful for a gallon of water. Works great
I have a 2017 yellow T/A with a black matte rood, hood and trunk. I have a few greyish spots the size of a pencil eraser on it that I have tried to remove with no luck. I have tried all of the recommended washes, cleaners, etc for matte finishes with no luck. Someone suggested a bit of alcohol. Anyone have any ideas?
