I have recently acquired several cleaned/refurbished/restored/NOS pens, and I have used them without treatment. Just read several posts about mold I wounder will these pens increase the chance of getting mold into my ink collection of 10+ bottles of ink? And will pen flush like the Goulet ones or J. Herbin ones doubled with an ultrasonic cleaner while doing pen maintenance help control and eliminate any possible mold? All my inks are contemporary ink that are presumably fresh and I read that biocide are used, will this make my collection less possible to be contaminated? I do rotate pen and ink so if something goes wrong I guess I have to disinfect every pen and dispose every bottle of ink.
