A while back I purchased a bottle of J. Herbin pen cleaner (Nettoyant pour stylo) from La Couronne du Comte and I just got a chance to try it out (on the MB I posted about in this thread. Anyhow, I don't have any huge revelations to impart or anything, but it is a very pleasant to use product and seems eminently suited to its stated purpose. It cleaned the pen pictured in the other thread well (as far as I can see... I'm sure there's lingering dried on ink in the works). It has a very pleasant orange-peel scent that reminds me quite a lot of those orange oil cleaners and 'goo/stain removers' you can buy at the big box stores. The bottle is 50ml and has instructions in French, German and English. RRP from La Couronne du Comte was € 5,95. I don't know if it'll be a regular staple for me, but as a one off and for special situations, it certainly makes a nice change from dish soap + ammonia. Pictures below (sorry, my phone was handy)... Warm regards from cold wet autumn-y Norway
