I used to save money by using a vinegar/water mixture in a spray bottle as my all purpose cleaner. It worked. I was satisfied. And it was cheap.
A few months ago I discovered this at Whole Foods (or Whole Paycheck, whatever). I was looking for something to get crayon off our walls, so I wouldn't have to paint. I found this and I LOVE IT. I use it for everything now. (except I still use Grease Lightening to clean the oven hood -- Well, Husband usually does that actually)It's $5 and some change, I think. But it truly is amazing. Give it a try if you're in search of something that cleans great, is a little more earth friendly and has a pleasant very light scent.
