Lately as I have been busy doing other things in the game, I am not cleaning them as much as I used to before. When I am doing something important in the game that will take a while, or something that I need to do, I don't usually clean my badges around that time or anytime soon. At times when I am bored or proud of something I did in the game, I'll clean them.
Since I have been working on other things in the game, I don't think I'll be cleaning my badges anytime soon though.
