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
Dry soldering refers to a poor soldering technique where insufficient heat is applied to the joint, leading to inadequate melting of the solder. This results in a weak connection that may not conduct electricity properly and can lead to intermittent failures. It often occurs when the soldering iron is not hot enough or when the surfaces being joined are not properly cleaned. Proper soldering requires adequate heat and clean surfaces to ensure a strong, reliable joint.
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.

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
Borax is used as a flux in soldering to clean the metal surfaces being joined and to prevent oxidation during the soldering process. It helps the solder flow more easily and create a strong bond between the metals.
Flux is used in soldering to clean metal surfaces, prevent oxidation, and facilitate the flow of solder. Cleanliness of metals is important in soldering because any contaminants on the metal surfaces can prevent the solder from properly adhering, resulting in weak or unreliable connections. Ensuring the metals are clean before soldering helps to achieve strong and reliable joints.
No, soldering and brazing fluxes are not the same. Soldering fluxes are designed to remove oxides from the metal surfaces being joined during soldering, while brazing fluxes are formulated to clean the joint and promote wetting for the filler metal in brazing processes. Additionally, brazing fluxes can handle higher temperatures compared to soldering fluxes.
You can safely store clean cutting boards in a dry and well-ventilated area, away from any sources of contamination or moisture.
