1 cup Dr.Bonner's Peppermint castile bar soap
1/2 cup Borax
1/2 cup Washing Soda
Grate the bar soap with a parmesan grater then mix with the other 2 ingredients and voila! you are done.
By using a natural soap instead of detergent you will you no longer need fabric softener. I once read that chemicals in detergent is what causes static cling. It took about 3 washings before I noticed a difference when originally switching over. In the interim you may want to add a little vinegar to the rinse cycle until the problem is gone. It worked for us.
