Just a warning on the Magic Erasers: they work wonderfully but don't scrub too hard without checking your progress, because it removed paint from my wall!
Here's a tip that I use the most around the holidays: we go through tons of candles, and the leftover wax is always stuck to the glass. Instead of trying to scrape it out, put the candle holder in the freezer (I'm not sure how long, we usually just check the next morning or in several hours) and the wax will just pop out, because it shrank.
Thanks for all the tips!
