Review on 🔧 Hakko FS100-01 Tip Cleaning Paste 10 g for FT-700: Restore Optimal Performance with Powerful Tip Cleaner by Jason Taylor

very expensive for what you get. This works a little better than a piece of solder with some rosin flux. However, using an acid-based flux on a piece of solder works better than this. it is too aggressive for routine maintenance, corroding the iron coating on the tips. I suggest if the rosin flux isn't enough to remove the oxidation just dip it in some sanitary flux, only do this if really needed.
