Clean your chain with any sort of detergent. I use Dawn dish soap and then use a lube that doesn't build friction through heat. And is clean after running a few weeks of riding. If your lube changes color rapidly, like grey or black and is thick from picking up debris it's time for a change.
And three with lubes less is more and should be maintained like the air in your tires.
SRAM 9-Speed PowerChain II™ Chains
Delivering light weight, strength and smoothness to your drivetrain. BlackBox™ racers know – SRAMŽ PowerChain™ is designed to stand up to the toughest courses and competitors. From the convenient PowerLink™ connectors that eliminate the need for tools to the GLEITMO™ lube that protects against dirt and friction, these chains set the standard for durability and reliability.
Shimano suggests (strongly) not to use an alkaline cleaner on their chain.
I think I'd go with the manufacturers recomendations here.
