Cleaning Synthetic saddle

Last summer, I bought a brand new wintec synthetic western saddle and since its either been in the house during the winter or at the arena where I ride, its gotten a little dusty. How do I clean it? Do I just use a damp sponge/towel/cloth or are there special cleaners for synthetic saddles?????

Hose it off, and let it dry. Yes, really.

Or you can just sponge the dusty areas off with a damp cloth. Do NOT use any leather cleaners on it.

Oooh ok. Thanks :)
