Never file the tip to clean it or form a different shape. Usually touching the tip with rosin-cored solder will supply enough flux so that oxides can be removed with a damp sponge or dry cleaner.

How to clean solder tip. A clean tip is bright and shiny. Be sure that the entire tip is covered by the product. Scrape the carbon off you can use some steel wool or fine grit sandpaper here but be careful here as you may scrape off the coating or scratch the tip.
Use a damp sponge to wipe away the black oxidation from the tip of the soldering iron until the tip is silver and shines in the light. If this isnt sufficient you can purchase tip tinner cleaner or also called Heavy Oxidation Removal Paste that are a mixture of solder paste and flux. Use isopropyl or rubbing alcohol on the circuit board terminals to wipe off the residue.
While the soldering iron is at full temperature roll it in the tip tinner. Cover the tip immediately with solder after cleaning to prevent further oxidation. A clean solder tip will also allow better conduction of heat.
After every cycle and before you start to solder always clean your tip. If you do the tip will oxidize faster next time you turn it on. Tip tinner Plato TT-95 is a combination of lead-free solder and cleaner.
A clean soldering iron will last longer and work more efficiently. Use fluxes Spongeless and metal wool to remove small amounts of contaminants from your soldering iron. About sandpaper use only sandpaper grit 600 1000 1500 or higher called High grit Ultra fine sandpaper- wrong way.
There are several different methods available to clean a solder tip. The first step of using a soldering pump is to clean off the terminal from unnecessary debris and rust. Making this a habit will significantly extend the life of a solder tip.
Let the tinning product melt around the tip then clean it as above with brass wool or a tip cleaner. The tips are mostly copper with a protective iron plating and once that plating is pierced the tip will die quickly. This video will show you how to clean your soldering tip and maintain it for many years of use.
Repeat the steps above until the tip is. For proper functioning and to extend their life proper cleaning is required Before During and After use. This should leave the tip of the iron with a layer of solder on it.
Keep the Solder Tip Clean. Pete Jenner Field Applications Engineer at Weller provides us with some useful tips and too. Use a damp sponge some of the black should just wipe off very easily.
Weller offers a wide variety of soldering tools and accessories. Use alcohol and clean clothing to remove grease corrosion and oxidation from the surface to be soldered and from the tip. Ideally the tip should be cleaned during use and after each session and put away in a tidy state.
You need to apply the isopropyl alcohol on the soldering side and not on the electric components. Once at the proper temperature push the soldering iron tip into the tinner. One conventional approach is to use a damp sponge during use.
Step 4 Unroll a portion of solder then roll the hot tip of the iron from the end of the solder until it does one complete turn on the solder. Take either a wet sponge or wire wool. As you roll it it should change from black to shiny silver as the baked flux is cleaned off.
Wire wool has the advantage of not cooling down the soldering iron too much and you dont. When the soldering tip has turned black from baked on fluxes and no longer wets properly it is time for the cleaning tools of last resort. Copper is used because its an excellent heat conductor but if exposed to solder it will quickly dissolve into the solder.
