Defluxer spray, compressed air, or water.
They are too delicate use canned air like they make for keyboards.
A: The pad is not clean it has tarnish or wrong solder with not enough soldering flux. Finally not enough heat.
No, it isn't. That's why we use it to clean electrical equipements ( dry ice blasting). it can be added that is how circuit boards are tested for low temperature operation
Look at the 'bit', the part that gets hot that you do the soldering with. It should have an inclined flat surface on the end. If it has not, make one by using a file. Heat the soldering iron up. At the same time get the solder out, which should be tin solder with internal flux. When the iron is hot, quickly file the surface of the bit clean and apply the solder, which should immediately 'take' to the surface. That's it.
It is used to clean impurities away from the surface to be soldered or brazed. Many times it is included in the flux. The use of acid type of fluxes is actually detrimental to good plumbing , soldering practices because if the flux is not properly cleaned the joint will eat away from the corrosive action of the acid

The soldering stand has a wet sponge on it so you can wipe off and clean the soldering iron!

Make sure the soldering copper (tip) is clean and free of oxidation add some type of non acid flux and do not over heat
Clean and tinned with melted solder
to get the maximum heat at the tip surface
CFCs are man-made substances, which account for much of the damage to the ozone layer. CFCs were first used to clean electronic circuit boards, and as time progressed, were used in aerosols and coolants, such as refrigerators and air conditioners.
yes you can, so long as you clean the metal before hand like in usual soldering
A reel of solder used for joining electrical circuits together on circuit boards. Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.
