我有这条幻灯机的遥控用缆线，它已经有超过 40 年的历史了，现在电缆线的表面已经变得粘了，只要手接触过它，就会感到手指黏糊糊，而且洗不掉。

查了一下网上，很对人碰到这个问题，包括电脑电源线，有线耳机线缆等，究其原因，有说是随着时间的推移，身体油脂、保湿剂或润滑剂接触到电缆的表面。这些油破坏了橡胶电缆的表面，使它外表加速老化而产生的。

我尝试过各种湿巾，肥皂水，洗洁精，甚至409，但似乎都无法去除黏糊糊的残留物。这显然是橡胶老化过程的一部分，但是……我该如何清洁这个东西呢？试了上述所有办法后都不行，最后，我用了异丙醇，用粗布沾异丙醇对电缆擦拭两遍后，就已经完全清除掉了橡胶电缆表面的黏乎乎的东西，现在手摸之处都非常干爽，你赶紧试试吧。

我就是用上图的这个异丙醇擦拭的

Rubber Computer Power Cable now sticky – how to clean?

I have this slide projector remote control cable and it’s over 40 years old and the surface of the cable has become so sticky that whenever you touch it, your fingers feel sticky and won’t wash off.

I checked the Internet, and many people have encountered this problem, including computer power cables, wired headphone cables, etc. The reason, it is said, is that over time, body oils, moisturizers or lubricants come into contact with the surface of the cable. . These oils damage the surface of the rubber cable and cause it to age faster.

I’ve tried various wipes, soapy water, dish soap, and even 409, but none seem to be able to remove the sticky residue. This is obviously part of the rubber aging process, but…how do I clean this thing? After trying all the above methods, it didn’t work. In the end, I used isopropyl alcohol. After wiping the cable twice with a coarse cloth dipped in isopropyl alcohol, the sticky things on the surface of the rubber cable have been completely removed. Now the touch is very dry, you hurry up Try it.

It is Isopropyl alcohol USP, 91%!
