To remove all custom data is quite a drastic operation. I rather have the user explicitly select and delete that data (which can be undone immediately) rather than have an easy to click button. It's more difficult to select all/delete through absentmindedness than clicking that clear button by mistake.

Your idea seems to be better...
About "clicking on clear button by mistake" This can be bypassed by adding a confirmation box :D

Select all, then Delete or Backspace, then "Salvar e aplicar".
