Hello guys. I need some suggestions regarding my Lamy Safari Charcoal. I am attaching three pictures. The nib as seen in the picture has developed some sort of stain near the slit of the nib. I have tried soaking the nib in water for a couple of hours as well as washing it some liquid handwash. Nothing seems to remove the stain mark. Is it because of the ink I am using?
Next to the cartridge converter, if you zoom and observe carefully you will be able to see that some little amount of ink is trapped between the contact of the piston edge and the body of the converter. I have disassembled the converter, applied some silicone grease but still, ink gets trapped. It started from after one month of using the converter after the cartridge emptied.( I bought the safari around August last year). How to prevent this?
