How to electroplate the old copper tube?

1, keep your hands clean. At first, the surface can be rubbed with a board bag or rough pure cotton cloth, mainly to remove the dirty color on the surface, which can achieve the effect of polishing and hanging porcelain. This will last 2-3 days.

2. Next, it is similar to a plate of beads. Play with the bag with a soft cotton cloth or plate, and gently rub it, not too hard. Leave it on a plate for a week and let it dry. Its surface will form an oxide layer due to contact with air.
