Deleting IPTC data from multiple image files?

[jenscsj]

I have just added keywords to about hundred image files, just to find out it was the wrong set of keywords. Can you delete IPTC data from multiple files at the same time?
I have tried about everything, but it does not seem to work. I have discovered that you can select multiple files, delete IPTC data from the first file, write the empty list to the image, move to the next image and repeat the procedure just described. But it takes time.
Would be great if you can empty all IPTC keywords from multiple files with just one click

This is one important function that I miss - by mistakes or if I decide to rename a keyword by many pictures.
The program Jbrout have this function - but is not confortable to use
