End of day. I let the sticker residue soak for hours while I went about my day. Peanut butter is 100% plastic safe and 100% will remove sticker goo.
Now the only issue is the thread they used to sew on the velcro, if it is cotton or whatever it is, it broke when undoing the velcro being stuck to iteself. I need to glue on the broken off velcro bits and then this cover is done.
Nice and clean, goo free.... but now I feel like a snack!
