That example is a bit extreme. If you play with the settings a bit, you can come up with more subtle effects:
Another strategy for grunging things up and/or disrupting patterns is to find a nice, contrasty grunge image and apply it to the surfaces you want to change.
Go to http://www.cgtextures.com and look up the grunge category. Find yourself some filth that looks good and save the large version. Open the grungemap you selected and play with the brightness and contrast until the areas you don't want to see are white. Place the map over the object you want to dirty up and crop it to fit. Set the mode to multiply (keeps dark areas and makes lighter areas transparent), and the grunge map will look like it's part of your floor.
The attachments below should illustrate. The floor, the grunge, the modified grunge, and the two combined:

Wow, simple yet chewy.
Many many thank yous.
Wow, that is incrediably sweet! Perhaps closest to outside doors would be the heaviest concentrations of "dirt".

I've minimized the path stones, to free up bytes for grunging. I've reworked the windows (thinning and color, removed colored shadow), and grunged the stable floor.
I've only PS7 with no fiber filter, and which I couldn't replicate the finer nuances of with any other tool yet. I'm moving past this to grunging the floor tomorrow with the ~4k bytes.
Thanks again for the great tips and lessons, such as I've been able to absorb.
### Latest WIP ###
This is coming along really nicely. Looking forward to seeing this when it has been grunged.
Grunged floor, first attempt.
