I like this Leah at Suddenly Frugal. Check her out at http://suddenlyfrugal.com.
She had one segment on making your own laundry detergent. Now, I am not a huge proponent of cooking all your drugs and products—but those huge price tags on Tide and other name brands bug me!
She uses Arm & Hammer Washing Soda (not baking soda), 20-Mule Team Borax (calling all boomers), and a bar of Fels-Naptha soap.
2 parts washing soda, 2 parts Borax, 1 part grated Fels-Naptha (cheese grater). Some readers made it 2:2:2.
She uses ¼ cup per load.
She put the stuff in first, then the water. No bubbles.
Some people used a food processor to chop up the soap. Some pretreated with the Fels.
It even works in cold water.
How can you be frugal and use hot water?
