my vehicle wrap guy said the best way to get any stains out (grease,oil….etc) is to gently wipe isopropyl alcohol on the vinyl.
Diluted isopropyl alcohol would be a cleaner of last resort. It should be used very cautiously and in moderation, as it can cause damage.
It is always best to start with the least aggressive method first, and work your way up as required.
