All the keyboards I ever used have this problem: the keys I mostly use (WASD) get dirty and have almost greenish bits (almost like dirt) which I can only remove if I rub really hard with a towel or my fingernails.
Currently using HyperX Alloy FPS.
- I always wash my hands before using my keyboard
- I don't eat/touch anything dirty while using it
