How To Clean Soldering Iron Without Flux
Using excess heat can damage the circuit board oxidize and damage the tip and render flux useless in flux cored solder.
How to clean soldering iron without flux. Wipe the soldering iron with a damp cellulosic and sulfur-free sponge. Dip the end of your solder wick into the flux a little and heat it with the iron. To do so you will need something other than flux to break down the oxides on the metal surface without which your surface may be damaged or not properly cleaned.
Since you wont be using the entire liquid in a single go pour some approximately 100 ml of solution in a spray bottle and use it. In the first step organic solvents are used to remove flux residue. It will liquefy and clean up the wires so the solder sticks nice and securely.
Always wear gloves before you handle the ethyl and isopropyl solutions and start mixing them. This helps to prevent unnecessary accidents. In a pinch you can use a solution of white vinegar and salt.
Work quickly carefully and as close as possible to the soldering area for best results. You have to clean it before tinning and the easiest way is. Turn off the electricity source and leave the soldering iron for about 15 to 20 minutes.
Attaching a heat sink. When done correctly the liquid solder should attach to the cold screwdriver properly thereby allowing you to get rid of it from the surface. Thats how you can tin your new soldering iron.
You also can clean your soldering iron tip with a sponge while using it to keep it clean. Soldering iron only works if there is a temperature difference. I found that without solder it is very difficult to get the solder to suck into the wires.
