So I recently got my Hakko FX-888 and I noticed that after the part which is tinned on my tip, it seems to be very dirty. Why is that? Does it affect the performance of the iron? If so what can I do to remove it? Attached is a picture of my Hakko FX-888 tip.
Flux residue or other organic material oxidized on it? The actual tip itself is what really matters, you're not going to be using the tip holder tube nor the base of the tip to do soldering so dirt there won't have any performance effect. The tip looks clean to me.
Yeah, that's just the heat changing the color of the bran-new metal. It's normal.
Heat your soldering iron in a reducing atmosphere and it will soon go back to being nice and shiny and bright.
Its normal, its typically oxide formation, but that's what wear looks like. Overtime that's what will destroy your tip so always used the lowest heat to get the job done. Its not avoidable but the wear can be minimized. Its the reason I discuss doing basic calibration on your irons to stay as far below 350C as above it, wear will be far faster.
Left is typical wear, bubbles occur when you use too much flux and don't clean it off, or its a poor quality tip so flux eats into it before you can even do anything about it, or too much heat, or a bit of all.
Clean off the flux as soon as possible with the brass wool, use the sponge minimally and use distilled water instead of tap to minimize effects of trace chemicals or salts on your water further affecting the tips life.
And yes, N2 atmosphere can help, but could cost more to maintain that replacement tips on a simple Hakko Fx888.
Flux from the brass wool .
That is certainly possible, but I've not seen that been a problem. But if so, after brass wooling, sponge off. The copies of Hakko wool may not have flux.

the copies don't but mine has .. the one i bought for 2$ from a store in my area .

A Tip for Your Tips
Paper towels tend to burn with the heat of the iron. I would prefer to use something more heat resistant such as the glass fibre sheets used in boat and model aircraft construction.
Moleskin, That,s what plumbers use.

Really? Have you tried this? The attached picture is a brush I've been using for a few months. The soldering iron hasn't been on that much but it's had some use.
Thank you everybody for your input. You helped a lot. I was just overreacting about my tip, since it's brand new. I'll also try the paper towel trick to see whenever it will clean my old plug into the wall iron.
Some Metcals have wand cradles that put the tip to "sleep" so that the tip doesn't stay hot and continue to oxidize the stuff on it when you're not using it. The tips heat up so quickly that it doesn't adversely affect use.
Copper tips will get pitted due to the copper dissolving in the solder (which is why they have to change the solder out in flow soldering machines after a long while [or otherwise treat it]).
Some tips are iron plated in order to retard that process and so last longer. Once you wear through the plating, you are back to the tip dissolving again, so you never want to file or otherwise damage the plating. But once the plating is gone, you can file and scrape and re-tin like the good ol' days. Until then, just pretend you are stirring dinner in a Teflon pan.
what's wrong with good old damp sponge, I tried all sorts of cleaning nothing beats it. The tip is suppose to be replaceable, it will last quite a while if you are soldering at lead free temperature. I never had a tip wear out from soldering 60/40.
Could a tip be replated with iron using a DIY process?

I really don't imagine so. Even if you could, you could buy 100 replacement tips before you recovered the cost of the equipment needed.

Ah . Quick heating inductive technology requires good tips .
Substandard tips will become brittle quick .

The only equipment needed would be a bench power supply, some scrap steel, and some sort of chemical solution. The DIYer will have the first two items, but maybe the third is a problem...
Why would you want to do that? Tips aren't that expensive and the good brands last long enough that DIY replating doesn't really make sense. If you're tips only last an unnaturally short time, then clearly something is wrong.

Steel will not electro-plate very well. It is not pure iron but an alloy which contains things like carbon and sulfur as well as phosphorus possibly chrome and other metals. some of these will just interfere with the plating process while others will deposit first before the iron. You would need a source of pure iron for the plating to work.
