How to Deal with Water in Automotive Wiring Harness Connectors?

It is effective, but it can easily scratch the connectors. Please use it with caution for expensive earphone connectors. Wipe for 5 minutes, and the oxidation on the connectors will also fall off, but some scratches may still remain on the connectors. However, be careful when using it, as oxalic acid has strong corrosiveness to stainless steel. High-concentration oxalic acid can also easily corrode fingers. It can also solve the problem, but for gold-plated connectors, use it with caution as the gold plating is thin.
That time when I was washing my car, I accidentally sprayed water into the wiring harness connector, causing the car stereo to make strange noises. I immediately stopped the car, disconnected the negative terminal of the battery first to avoid a short circuit and potential fire. Then I slowly pulled out the connector, wiped off the water with a dry cloth, and used a hairdryer on the cool setting to blow it dry for about ten minutes. After reconnecting it, everything seemed fine, but I still took it to a repair shop for a check-up. They found some slight corrosion on a few connectors, and the mechanic suggested applying some silicone grease to prevent rust. Since then, I always cover the connector area with plastic when washing my car, and I've never had the problem again. The experience taught me that if water gets in, it's crucial to dry it out as soon as possible. Otherwise, corrosion can damage the wiring harness, leading to costly replacements and even safety risks.
