How to reset video settings?

Some video settings are always re-enabled after restarting because I've used some mat_* commands in the past. I've deleted video.txt file (where video settings are seemingly stored) in ~\Counter-Strike Global Offensive\csgo\cfg\, this had no effect.

Is there a command to reset video settings, as clearing configuration files appears not to work?
