Welding Acid AG 35ml features:
Prepared transparent liquid, acidic, corrosive.
Prepares and facilitates welding on nickel-plated surfaces.
Apply a small amount of the preparation on the element to be welded, and then wash it with water. CAUTION:
Dangerous preparation, contains up to 35% phosphoric acid. In case of contact with skin or eyes, wash with plenty of water and consult a doctor. Keep closed and out of reach of children. It causes burns. Risk of serious eye damage.

It allows removing the solder residues from the tips.
It cleans better and does not cause temperature drops like with sponges.
You do not need extra water to clean the tip.
Easy and effective cleaning at the tip.
