So today I've retrobrighted the keyboard. I've dismounted the keyboard but I didn't take out the keys as I think it's better this way so all of the keys were facing upwards for retrobrighting them. I've used a 20% volume peroxide solution with active oxygen for laundry for two days as it was a bit cloudy.
I'll try it tomorrow to see if it works and also the formerly not working keys. I'm very happy with the result so far
