Due to the contact with seawater, the surface of the transmission contact is covered with oxides after a period of time, resulting in poor contact.

When zoomed in, the internal contacts have also been oxidized, and the surface is covered with copper oxide. The picture on the right shows that the outside has been wiped, but the inside has not been wiped; the internal contacts are still covered with white-green oxide before wiping;

Dip the copper oxide wiper CuP01 with a lint-free cloth, and wipe the oxidized contacts.

After wiping with CuP01 copper oxide wiper, the oxidized contacts recovered clean and bright metallic luster.

In actual use, it can also be connected to a computer to transfer photo data smoothly.

Comparison: before wiping on the left, after wiping on the right.

Comparison: the picture on the left shows that the outside has been wiped, but the inside has not been wiped; the internal contacts are still covered with white-green oxides before wiping; the picture on the right is that after wiping, the golden luster has been completely restored.

More detailed contact oxidation is not easy to remove. It is very troublesome to use abrasive materials such as "toothpaste" to wipe off the oxide layer of the contact, because
1. If the abrasive paste cannot be wiped with force, the effect will not be obvious.
2. After wiping, toothpaste-like abrasive residues are not easy to remove.
3. The abrasive paste may wear the contacts, affect the accuracy, and cause poor contact. Using CuP01 copper oxide wiper will not have the above problems. CuP01 copper oxide wiping agent can evaporate quickly, leaving almost no chemical residue on the contact; it is completely soluble in alcohol, and wipe it again with alcohol, which can ensure the strict quality control that requires extreme precision and no residue.

Gold finger before cleaning, the surface is covered with chemicals, resulting in poor contact.

Observed with a microscope, the surface is covered with oxides.

Dip the copper oxide wiper CuP01 with a cotton swab, and wipe the oxidized gold finger.

After wiping with CuP01 copper oxide wiper, the oxidized gold finger will restore clean and bright metallic luster.

Observed under a microscope, the oxide attached to the surface has been completely removed.

Comparison: before wiping on the left, after wiping on the right.

After being used for a period of time, the surface of the gold finger is covered with oxides, resulting in poor contact. Similarly, in order to avoid poor contact due to oxidation, packaging factories often use abrasive materials such as "toothpaste" to wipe off the oxide layer of the contacts before packaging. But this action is a bit troublesome, because after wiping, the residue of toothpaste-like abrasive materials is not easy to remove. Using CuP01 copper oxide wiper will not have the above problems. CuP01 copper oxide wiping agent can evaporate quickly, leaving almost no chemical residue on the contact; it is completely soluble in alcohol, and wipe it again with alcohol, which can ensure the strict quality control that requires extreme precision and no residue.

CuP01 Copper Oxide Wiper can be applied to any copper material and can quickly wipe off copper oxide.

CuP01 copper oxide wiper evaporates completely after wiping.

Dip the copper oxide wiper CuP01 with a cotton swab, and wipe the oxidized gold finger. Before the gold finger is cleaned, the surface is covered with oxides, resulting in poor contact.

When wiping, wipe the oxidized part back and forth with a cotton swab. No need to follow a certain order or direction, CuP01 copper oxide wiper can evaporate quickly, leaving almost no chemical residue.

Safety precautions: CuP01 copper oxide wiper contains more than 90% isopropanol, and its toxicity is similar to that of ethanol (alcohol); if it is used in large quantities in spaces with poor air flow (such as clean rooms), special attention must be paid to ventilation to prevent workers from exposed. In addition, avoid direct contact of the agent with hands or skin. In case of contact with the human body, wash it off with clean water immediately.

When wiping, wipe the oxidized part back and forth with a cotton swab. No need to follow a certain order or direction, CuP01 copper oxide wiper can evaporate quickly, leaving almost no chemical residue.

CuP01 copper oxide wiper is completely soluble in alcohol, if you want to ensure the strictest quality control without residue, you can wipe it again with alcohol 1~2 times.
