Got into 3D printing ... learned how to clean up a hotend

Well, while I'll never will be a real blogger ... as you can see how long my blog posts are spread apart ... I occasionally have something I want to blog anyway.
And here it is: Tips to clean up a hotend from filament stuck to it:

Anyway here is what I learned in the cleanup process.

1. If you have a 3D printer buy at least a sample of Nylon filament, in any case of cleanup it comes in handy.
   
2. Don't use metal tools to scrape it off, they leave scratches making further cleanups (maybe possibly potentially) harder.
   
3. Everywhere where is no smooth surface it is a pain to clean (up to some nooks and crannies that are impossibru).
   
4. The residue becomes soft at as low as 120°C where I suggest you start clean, then step up the heat in ~10°C increments while you clean, if the stuff refuses to come off. Keep the temperature as low as possible, tho to minimize the stress of the hotend that isn't cooled while you clean (cause you have to remove the fan to do so). Keep the temperature below 200°C in any case.
   
5. Cut sharp corners in your filament it helps to scrap off stuff. And gets you in nooks you otherwise won't.
   
6. Use a tool with round edges like needle nose pliers to press the nylon against the residue (pliers closed, just as a tool with non sharp edges so you don't leave marks in case you slip) cause otherwise you might leave scratches (e.g. when using a screwdriver), burn yourself (when using your fingers), or don't have enough pressure (when using nothing to press the nylon down).
   You probably also can use tweezers, but since you don't need it to hold the filament, but only to press it against the hotend they have less use.
   
7. Sometimes you want to use the sharpened tip, sometimes you want to use it length wise.
   
8. Cut the nylon filament when its surface is dirty.

Well that are all tips I can relay for now. I hope that might help someone else in future.
