I've found before the December patch that Cleaning frenzy worked well. If there was just a dirty sink, the option was there and it worked. Now, if there's a dirty sink, the option either doesn't show, or when you click on it, she just stands there staring into space until you cancel the action and do it by hand. Also, I'm finding that if she has the uncomfortable moodlet from this, and the option doesn't show up, that there's maybe a glitch. Check your sims personal inventory for spoiled food. If it's there, clean it out. This seems to all lead up to the "fridge Won't work" glitch which I solved by repairing the game. If you don't want to repair the game, hire a maid, then travel off the lot and back to see if the maid found what you couldn't. Good luck!
