Advice on Dirt

I've just started a scene of a mage with a dragon. However, I think the first render has a huge problem, both the tunic and the dragon's horns are way too clean. What is the best way to dirty them up?

Hiya!  Fuseling sells a couple of great dirt products:

For the horns you can change the base color to a dingy and washed out pale yellow ocre or ivory color For the tunic I would choose a pale washed out dried dingy straw color. You can still add the dirt products if you like..

If you don't want to use PS to tamper with the maps there are also these two.

I think that A touch of dirt is probably be closest to what I'm looking for but it isn't on sale right now. So I think I'll try changing the base colors and editing the image in a paint program after.

So I was tinkering with the base colors and got a menu called the Layered Image Editor. Using it I created a new layer, loaded an image of some gray blobs and smears to the layer, and then set the layer to multiplicative. Here are the results.
