sed

I've the CSS file with many entry like

id1, #id2, #id3, #id4 { ... }

id3, #id2 { ... }

id2, #id4 { ... }

I want to extract list of unique IDs using command line tools (msys). Unique means any entry in list presented only once. How?

PS: I know how doing it using python, but what about awk/sed/cat?
