Hey, since it sounds like you're not really familiar with spellcasters-- Scruberoo works on other sims too, and most objects! Almost anything but plates can get that cast on them.
Oh, and Waterfall in a Bottle-- kind of useless for hygiene, but if your sims catch fire they'll use it to put themselves out. I've never been attacked by fireflies, as many times as I've been there, but they have set themselves on fire from failed traps.
