I used Zaino Leather Soft spray cleaner on my black dashboard without realizing that my dashboard is vinyl. A day afterwards, I had dark grey areas on the dashboard where I guess the cleaner bleached the vinyl? I can't tell if it is bleached or if it is an oil left behind by the cleaner. I tried a vinyl cleaner on it, but the grey remains. Someone suggested that 303 Aerospace Protectant will make the dashboard black again but I am wary of putting a protectant on it if the grey is realy just Mink oil. Wouldn't that seal it in for good?

 

You may want to try cleaning it with a vinal cleaner first and get up as much of the leather cleaner as possible.I've seen many products on the market that are conditioners for black vinyl,check out www.properautocare.com they have a few products that may be just what you need.
