Today I made my own laundry soap. I've been toying with this idea for a while, but I was put off by the recipes for liquid soap, and the vision of a 5-gallon bucket of it in my laundry room.
Instead, I made a powder soap. Here are the 3 ingredients you need. All three of these are sold at our local WalMart.
1 bar Fels Naptha soap (it's about 5 oz.)
1 cup washing soda
1 cup Borox
Grate the bar of soap. This is the only tedious part. I should have grated it on a finer setting, but, um, I'm a wee bit lazy.
