WD 40 on rusted RCA plugs?

發問:

I have a rusted RCA plug that I would like to use. Since I don't do much DIYing, I don't have different sprays and don't want to spent money to purchase a can just to clean a single plug. I do have a can of WD-40, some say that it sucks out the moisture (which is good) but forms a layer of insulation... 顯示更多 I have a rusted RCA plug that I would like to use. Since I don't do much DIYing, I don't have different sprays and don't want to spent money to purchase a can just to clean a single plug. I do have a can of WD-40, some say that it sucks out the moisture (which is good) but forms a layer of insulation (bad), WD-40 official website says that "2. DISPLACES MOISTURE: Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.", making it suitable for electronic contacts? I don't know what to do. Any cheap home solution? Alcohol?

最佳解答:

回答用中文, 如要英文我再補充。 WD40是潤滑油, 常用於機械潤滑使用, 其產生的油膜可以抗鏽, 但不具腐蝕性。個人建議: 音響RCA 頭的修復, 用WD-40 是可以的, 有時我也是這樣做。先用WD-40 噴過RCA頭生鏽的部份, 等一些時間如15分鐘, 鏽漬溶解之後, 用紙巾/棉花棒揩除鏽漬及過多的油性便可以使用了。如果你用火酒洗掉那層油性, 恐怕個頭失去保護膜會再生鏽。但電路板上就不建議使用。火酒不能溶解鏽漬。

其他解答:

硬碟要找硬碟醫院，能救回來才重要，我司就是找他們做出來的必須要推，當初心急亂找錯店告訴我沒辦法，後來找又找到硬碟醫院，我告訴他真心要來救援，可以等，在他們努力下有找回來太棒了，原來微軟張經理都找過他們 http://www.datamaster.com.tw|||||您好，我推薦您一個網站，一個對手機設備，攝影設備最新產品價格以及產品評測的網站，上面還有很多實用的小技巧，常用知識。 http://www.digital-price.net 希望對您有用
