I Restored This Yellowed Keyboard for My Home Office - Retro Tech Restoration

Since everyone, including me, are working at home offices now I decided to restore this yellowed retro KeyTronic keyboard. It’s quite yellow and dirty, one of the keys even got stuck when I tested if the keys move properly. I will also connect it to modern laptop with only USB connectors. The original color of the keyboard is beige so it will have slight yellowness to it anyways but you will see the difference in the end. This model is an ergonomic keyboard. You can tell it by the curved base for the keys.
