One of the easiest, most convenient money-saving ideas I have used in my household is making my own laundry soap! Its VERY easy, and ends up costing pennies per load. The convenience of being able to whip up another batch vs. going to the store when you run out is the best part.
Gather your ingredients. You will need a bar of laundry soap. I use Zote and only use half of the bar per batch. Some people prefer Fels Naptha, but I feel like Zote is a more aggressive detergent, and more economical because I only use half of the bar. You will also need water, Borax, and washing soda. I was able to find both the Borax and washing soda in the laundry aisle of the small grocery store by my apartment. You will also want two quart sized canning jars to put your soap in.
The process. Start by grating the bar of soap. Then put 4 cups of water in a stock pan over medium/high heat, and once the water is warm add the grated soap. Lightly stir it until the soap is melted. Turn off the heat and then mix in 1 cup of washing soda, and 1/2 cup of Borax. Pour the mixture equally into the two canning jars, and then add water to the jars until they are about 3/4 full. Tightly screw the lids on, turn the jars upside down, and let them cool for a couple of hours.
Once the jars are thoroughly cooled, (turn them right side up!) unscrew the lids. Now unscrew the blade from the jar of your blender, and then screw the blade onto the top of a jar. Give it a whiz on the blender until your soap is creamy and blended. Put the original lid back on and use about 1 tablespoon per load of laundry!
Use some caution when storing these jars so they don’t vibrate off the top of your dryer (don’t ask me how I know). Once you switch to homemade laundry soap you will wonder why you have been paying so much for store-bought all of these years!
