I've already vacuumed and cleaned every interior surface, removed the back seat to vacuum and bleach under it, and bleached all under the trunk liner. I've even cleaned the engine bay out. Now, it primarily comes back if the air gets put on recirculate or I roll down the window while at a drive through window.
Any ideas as to what I'm going to have to do to get rid of this?
