Miamijim, what's the harm in removing your chain to clean it if you've got an SRAM, or have installed a power-link (or whatever they're called)?
Every time a chain is dis-assembled the risk of damaging a link is there. Regardless of the mechanisn used to secure the chain, 'power link' (I just love the marketing behind that term), a pin, or master link (power link just sounds tougher doesnt it). There is minimal harm removing a chain with a 'powerlink' but I have seen those fail. Eventually the removable link can get 'loose' and come off with minimal effort.
KISS...Keep It Simple Stupid....when it gets dirty clean it...when you clean it lube it....when it gets dry lube it....when it gets noisy lube it.
