Caching google maps etc by Eastpak1984 - 2013-08-13

Is there a simple way to clear out the old notes like

CODE

*Begin GMapShot* <img src='http://maps.google.com/staticmap?center=53.52075,10.102617&zoom=MaxZoom()&size=300x300&format=jpg&maptype=hybrid&mobile=true&markers=53.52075,10.102617,blue' Alt='Google map'/> *End GMapShot*

?

I have about 1000 Caches with this text in the notes, and I can't replace it with "nothing" because some caches have additional, important information in the notes.
