Wondering how people clean their motorcycle leathers?

We've had a few hot sweaty days and don't want the inside lining and neoprene to start smelling bad. Unfortunately the lining cannot be removed.
For now I've sprayed Milton on the lining and massaged it in, ensuring it doesn't soak into the leather. Hopefully it will air dry quickly. Anyone have any better ideas about maintaining the insides of your bike leathers?
