Marvicide / Barbicide In Ultrasonic Bath


Recommended Posts

I finally invested in one of the lesser-priced ultrasonic cleaners offered on Amazon. I have been happily cleaning eyeglasses, pens, and anything else within reach that needs to be cleaned. Since it is stainless inside, I put some Marvicide in there and cleaned a few DE razors. I let them soak for 15 minutes and then ran them through the three minute cycle twice. PEN RELATED QUESTION: is Marvicide or its more popular cousin, Barbicide, safe for fountain pens? It is diluted according to package directions. I thought it better to be safe than sorry. Thanks,

As always, Your Mileage May Vary! I am not suggesting the use of these disinfectants for your most treasured pens, or expensive pens, or celluloid, casein, piston fillers with cork, etc.


I tried it out today. I have two circa 2006 Wality piston fillers. One has a few combs broken off of the feed, and the other has a nib with a gouge / knick/ cosmetic defect. They both have steel nibs. I put them in the ultrasonic filled with Mar-V-Cide for the three minute cycle with the pistons filled with solvent. Afterward, I was able to pull the friction fit feeds and nibs, completely disassemble the rest, and run them all through again.


I was amazed. I cleaned these by flushing until the water ran clear before I put them in a box many years ago, thinking they were clean. There was enough Vert Olive in one to discolor the water completely. The other one had remnants of PR Plum to add to the mix.


After rinsing with water and air drying, I made one decent looking pen, and kept the rest for my parts drawer. The piston is greased and operating smoothly. I am going to use this pen when traveling just in case it doesn't come back home with me.


So encouraged, I decided to run an oversize Wality eyedropper pen though. I didn't disassemble the section this time. I am pleased with the results. In fact, instead of putting the eyedropper pen away, I have decided to use it for ink samples since I can get it so clean between fills.


Best regards,

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Ah Ruaidhri ya wee heid banger, you do indeed have an Irishman’s way wid dose words now. I’ll be from outer Aberdeenshire up in the blizzard riven braes of the Grampians.  Amateur medicine and surgery is it? Well what noble aspirations you do possess, we need to encourage such noble experimentations.  I pondered on leaving my own battered shell to science, but, until I read your pearls of wisdom and lament, I had comedown on the side of leaving my body to Findus frozen foods.  However, your rema

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
