Fabric Softner
Add white vinegar (½ cup) to the last rinse cycle when washing your clothes. If you have a place where you are supposed to put your fabric softener (our washer has a little holder right in the middle of the agitator), then fill it with the vinegar like you would fabric softener. It should hold about ½ cup - at least ours does.
The vinegar will not only soften your clothes, but it helps rinse all the detergent out of your clothes. If you want a little fragrance, add 25-30 drops of essential oil to your gallon of vinegar and shake up.
