I have an 03' GT. I noticed that a lot of dirt seems to get into the area where the trunk is mounted and I can not seem to get anything to clean it out with that will do a good job. What is everyone else doing to get the dirt out. it is such a tight space. very bad design!!!!
First, take anything of value out of your trunk. Then get a good, strong degreaser, and spray it onto the area you want clean. Let it penetrate for a minute or two and spray it off with a hose, or a powerwasher if you have one. You may have to repeat the process once or twice depending on how bad it is. AFter you're done spraying it, wipe it down and you're done. It's quite simple actually.
