Wow. I am thoroughly impressed.
The homemade laundry detergent I posted about almost a year ago has been not only earth friendly and efficient, but majorly cost effective as well. I spent around 13 dollars for all of the materials. I made a double batch every 2 months or so and I just ran out of ingredients today! 13 bucks for a year's worth of laundry! Mind you- this is for a family of 5! In terms of time and effort, I calculate I spent about 30-45 minutes total this past year making detergent. That is incredible to me- that it can be so cost effective AND minimally time consuming.
I love it when experiments work out!
