I got a Pilot Custom Heritage 92 Clear Demonstrator for christmas. Do I run into any danger zones if I use the Goulet Pen Flush to clean up my CH 92? Beautiful pen, will probably be my favorite from now on. My common sense tells me that: 1. Flush chemicals may haze the clear plastic. 2. Flush chemicals may slowly eat the piston seal or make it brittle. I don't want anything to happen to my pen. It is too precious!! Please throw all your knowledge at me! Ty!
