Another newbie to the forum here. I've got a couple small spot stains on the ceiling of my 2019 Ranger Lariat. Wondering if anybody has any tips/tricks to effectively clean them without damaging or further staining the ceiling. When I say small, they're roughly the size of a pencil eraser. One might be the size of a dime. Sadly, I'm unsure what they're from as they were there when I purchased my truck. Any help would be great, but it's a small inconvenience in the big scheme of things.
