how to clear oxidation

Hello friends. There were unlit bulbs in my car's 3rd stop lamp. I removed the lamp, replaced the bulbs. however, the bulb housings have turned blue-green, oxidized. The lamp is still on, but not the lamp. How many times did he go out? not burning at all right now? the same is true for other lamp sockets. How can I remove this oxidation using & nbsp; and what. I am waiting for your advice.

electricians have oxide-removing sprays. I recommend they do a good job. .It was not bad :)

WD-40 spray is available on the oxidized floor, gently and lightly grind, nothing remains: D

thank you for the advice. spray is also a good idea, but I cannot sand it. Sanding does not reach places such as the inside of the socket and the housing of the lamp.

The contact will see the spray heat.

& nbsp; Yes, contact spray will do your job, but it is very important to prevent short circuit.

thank you. let me investigate tomorrow contact spray.

I think the best solution is wd40

philips contact spray blue box oil-free type scraping sanding no need

dirt rust remover from bim works very well

Thank you very much for your suggestions and interest. I went to the electrician today. The problem is not oxidation. It took an hour and a half. solved the problem. He received a fee of 40TL. now it works smoothly. & nbsp;
