I searched the forum and couldn`t find anything so I`m thinking this really IS impossible. But has anyone found a way to clean the trunk liner in our cars? I have a 2014 2LT, but I think they all use the same material. Kinda like the fuzzy part of Velcro that has the same effect on dirt/debris. I tried to use a good Shop-Vac but to no avail the dirt is still there. Do I need to find the secret? Thanks, Jeff.
