Figured out why my soldering iron tips kept oxidizing so fast

I was going through a tip every couple weeks on my Hakko station and it was driving me nuts. Figured it was cheap tips or maybe my flux was bad. Turns out I was leaving the iron on at full temp for hours between uses. I'd walk away, get lunch, come back, and it just sat there at 700 degrees with nothing to do. Read a post on here about turning it down to standby temp around 300 when idle and using tip tinner before putting it back in the holder. Tried that for a month and my tip still looks new. Cost me maybe $30 in wasted tips before I sorted it out. Anyone else run into this or have other tricks for tip longevity?

Running into the same problem myself a while back. Switching the iron down to 300 when stepping away totally fixed my tip oxidation issue. A quick dip in tip tinner before putting it away also helped keep the tip coat fresh.

The trick nobody talks about is that your tip coating actually degrades faster when it's clean and shiny than when it has a thin layer of solder on it. I stopped wiping my tip on that brass sponge every single time I used it. Now I just dab it on a damp sponge maybe once an hour and leave a little blob of solder on the tip when I set the iron down. That little puddle of molten solder acts like a shield against oxygen. Been doing that plus the standby temp trick and my current tip is going on six months with zero issues.
