Degreaser
Hey Dirk, I use one by PPG , DX 330. It's one of the mildest ones out there. It won't hurt or remove your airbrushed graphics. I've haven't had and issues of any kind with it. Some of them are pretty harsh. Tumbler is one that comes to mind, whick willl take the hide off an elephant. Hok has a water baes one to, I believe that one is KC 20 if I'm not mistaken. This works well for cleaning for sort of in between work in progress cleaning.
