The closest I have come to making my own detergent is by using baking soda and vinegar. I noticed the mosquitoes don't bite as much either! I am a big advocate for vinegar & baking soda. My husband does not like the smell of vinegar, but he agrees with the benefits. Smart man!
Funny! My DH was both amused and concerned! But he's seen how well all the homemade cleaners, etc work, so he's a convert.
Homemade laundry soap was my first big step. Then I went a little nuts. I have labeled spray bottles around here for about everything. Our house has never been cleaner for so little money!
