My ink samples for my first pen arrived yesterday, and I am still waiting for my first pen to arrive in the mail, a Lamy Vista. When I looked at the ink samples, I noticed immediately that the sample vial of bsb was totally stained with blue, and none of the other samples had any staining at all. With all my research online, I knew that bsb has a reputation, but the color is just so breathtaking! I am now having second thoughts about putting this ink into my pen. If (when) staining occurs in my Vista, will an ammonia solution be able to get it out? I have heard of some issues with using bleach with steel nibs and some rubbers, so I am a bit off put about using bleach. Also, I don't know how many of you are aquarium people, but I have a bottle of Dr. Tim's brand ammonium chloride solution for "fishless cycling" of a tank; would this work to clean a pen, or should I avoid it? Sorry for my ramblings here, but hopefully some of you can help me. Thanks!
