When any of my blue switch keys start having key chatter, I apply a few drops of isopropyl alcohol and pressing and blowing into the switches. This usually removes the key chatter. For example, today I had key chatter on my W key so I did the usual steps and it got fixed, however, a few hours later my D key started having key chatter so I did the usual steps to remove key chatter and it got removed but after about 30 mins, the D key lost its click. I tried the usual key chatter removal steps again and it temporarily regained its click but then lost it after about 20 mins. What can I do to restore the blue switch click without desoldering?
