I was replacing some old screws in the dash of my 71' Lincoln with new stainless ones, and in between I was using some generic car cleaning wipes on my dashboard. It is made of what looks to be a hard black vinyl. Since I was sitting in the passenger seat, I only scrubbed that side. The wipes took up years of brownish dirt, but there are what appears to be grease stains on the vinyl from probably hamburgers and fries. The cleaning I did also made the vinyl very light and chalky looking as compared to the untouched side. I need a recommendation for a good deep vinyl cleaner to get more grime, grease, and stains out, but also hopefully one that won't leave the surface so dry and faded. I also need a good protectorant as well for after the cleaning, to restore color and luster to the black vinyl. Any ideas? Thank you in advance.
