How do you clean out the Lamy 2000 fountain pen?

[Charlie737]

Hello.

I have just bought my fifth fountain pen, the Lamy 2000 which when the shipment arrived, had a deadly surprise. I had not looked very far into the pen but it turns out that the pen is piston filled with a unique nib placement. Because the nib is so hidden, i have no idea how to take out the nib to clean it. Help me!!!

Water flush. That's all I have done, though I've only owned mine for half a year.

Normally, I too just flush with water by iteratively filling, expelling, filling, expelling, etc.

Once the water ‘runs clear’ when expelling it from the pen, I refill it with water and then let that ‘wick’ through the nib into a folded piece of kitchen paper. I repeat that step until no more dyestuff wicks out of the nib into the kitchen paper.

I perform this ‘OCD-esque’ routine every time that I run out of ink, because I like to ‘rotate’ between my pens, and between my inks too. Although it is not ‘unknown’, it is unusual for me to choose to re-fill the same pen with the same ink, and so even my Lamy 2000 can find itself unused for a few months.
I do this extensive clean for each pen with water at the end of each fill because doing so means that I can be confident that I won’t encounter any undesirable ‘alchemical’ conflicts (e.g. between iron-gall inks and pigment-based inks) when I next fill the pen.

 

All that said, I did take the front end of my 2000 off when I needed to re-lubricate its piston with some 100% pure silicone grease.
At that time, I availed myself of the opportunity to remove & rinse its feed thoroughly, although I cannot now remember whether or not I also took off its nib to scrub its underside.

It's great that you (apparently) can disassemble the Lamy 2000 if you really have to, but for flushing out old ink this would be overkill in my opinion (compare: when changing the oil in your car, you don't disassemble the engine either).

As Mercian said just water. In addition: if I flush a pen filled with IG ink I use a little ascorbic acid dissolved in water (AKA Vitamin C), as these inks like a slightly more acidic environment. I may at some point leave the water in overnight and see whatever it dissolved by just sitting in the pen. Only when needed I move on to a little pun flush (and then need to do flushes with water to get rid of the pen flush). Dissambly I reserve for repairs.
As said this is my opinion. The fact that you can take it apart doesn't mean you should do so on a regular basis (and certainly not when there are friction-fit parts involved)

This really wasn't a thing, in my recollection, until the TWSBI "here's a tool, take it apart" Curse, along with a dash of Noodlers.  So yeah.  Flushing will suffice.

Don't take apart unless you have to.  A flush and then shaking the water out is sufficient.  I've seen a number of 2000 pens that broke because the owner insisted on disassembling the pen to clean it on a regular basis, and then over tightened the section putting it back on - which lead to snapped threads on the barrel, or a lost seal (or improperly installed) at the back end of the feed.
