I have some treat on my black vegan seats. Based on everything I've read, baby wipes are the way to go. However, while effective with most dirt, they don't do anything for the sap. I'm worried that stepping up the "strength" of the cleaning agent will then do damage to the seat. Did anybody have success with something other than baby wipes? There are several threads about this with many options but each seemed to have a drawback in some way.
