Montblanc Site's Cleaning Recommendation

[dbj1971]

Interestingly, Montblanc's official site recommends cleaning the 149 with warm (emphasis mine) water. Now, this defies conventional wisdom that you should never use anything but cold water when rinsing/cleaning your nibs or you could damage the nib. What are anyone else's thoughts on this?

I normally use cold water but I don't think moderately warm water would cause any damage.

I am always using lukewarm water. Not the temperature you would like for a shower but something that is comfortable on your hands. Somewhat about 30°C. Works better than cold water and is still safe.

I hypothesise ink may dissolve and flush more readily with lukewarm water.

 

In practice, Luke warm or cold water makes little difference although hot water is certainly not recommended due to potential for damage to certain parts (e.g. temperature sensitive vintage materials, ebonite feeds).

 

The gold itself in the nib would tolerate water without difficulty.

Remember that you are not going to let the nib soak overnight in warm or hot water.A good rinse in warm water dissolves the ink faster as simple chemistry dictates.If you are not in a hurry let it rinse more time in cold water.

If Montblanc recommend it then they should know what is good and what is bad for their nibs/feeds.

 

I hypothesise the same as you.

 

Also, I tend to run it under running water which results in one hand getting wet. I don't like my hand getting cold (what a wimp) so the warm water assists to this too.

Generally, things happen twice as fast with every 10 degrees Celsius temperature rise.

 

So, rinsing in 20C water will dissolve twice as much gunk in the same time as rinsing in 10C.

Raising the temperature to 30C will double that again, and going up to 40C will double that again.

So, rinsing your pen in 40C water (lukewarm) will dissolve 8 times as much gunk per minute as it would in 10C (cool).

Thank you to all for your helpful replies. I appreciate all the input. I'll probably be asking more questions as I go along, some of which might be "elementary" stuff to some of you experts and long-time afficianados.

 

Have a great weekend, everyone.
