Usage introduction:  

First let the cleaning block absorb enough water, squeeze some by hand, and retain about 70% of the water. Take the soldering iron handle and rub the heated soldering iron tip on the cleaning block twice, the tin layer on it becomes bright, the soldering iron tip is also clean, and the soldering can be performed immediately.
Features:

1. Heat and high temperature resistant.
2. Soak in water and foam without sulfur.
3. The effect of cleaning the soldering iron tip is obvious.

The soldering cleaning sponge is placed on the soldering iron stand to clean the soldering iron tip. It can clean the oxide on the surface of the soldering iron tip without damaging the alloy layer of the soldering iron tip. Avoid oxidation of the soldering iron tip and burn to death due to overheating, remove solder residues, and keep PCB components clean.

Sprinkle a little water on the cleansing sponge during use, it will swell when exposed to water. The sponge needs to be soaked in water, not too much but not too little, and squeeze out the excess water so that the welding tip can be cleaned. If the cleaning sponge is not used, the solder tip will be damaged and the tin will not be applied.
