hive mind: cleaning a steam iron?

Does anyone have any good tips for cleaning a steam iron?

I've not cleaned mine in... awhile, and the steam no longer comes out. Speculating that this is due to mineral deposits gained through frequent use, I put a water/vinegar solution in the reservoir and cranked it up to high, with still no steam (though it heats up fine).

Do I need more 1) vinegar, 2) patience, or something else? Failing this, does anyone have reliable suggestions re: steam-ironing with a non steaming iron (spritz fabric with water, iron as usual?)

Anecdotes welcome.

word of the day

Found whilst looking for Blackadder iconage (I need one that has the "cowpats of the satanic herd" quote): snarksexual, because sarcasm is hot. Interests include the usual suspects: Blackadder (natch), Alan Rickman as Snape, Dorothy Parker, House. M.D. etc.

Sadly, the interests list far more snarky male than female characters, but whether this demonstrates the interests of the community creators or the dearth of truly sarcastic women I couldn't say.

wall of weird quizzes

I got 9/10 for the cryptozoology quiz; 8/10 for bigfoot.

Clearly I'm losing weird cred :P
