We've been fighting these allergies for years and I know how frustrating it is. DH has even been referred to some of the top allergists and dermatologists in the country and has stump them all...

Good Luck!!

Homemade Laundry Detergent:
-1 1/2 cups of Soap Flakes
I order my Soap Flakes online and found them to be a good price compared to buying bars and grating them. You can also grate a bar of Fels-Naptha or Castile soap. Fels-Naptha has some pretty harsh chemicals in it as well, so I stay far away from that. I have had success using other brands of Castile soap, though.
-1 cup Arm and Hammer Washing Soda
-1 cup Baking Soda
-1/2 cup Borax

HE directions:
Use 1 Tablespoon for a small/light load or up to 2 Tablespoon for dirtier loads. Put soap directly in the washer with your clothes and not in the soap dispenser.
Regular machines:
Use 2-4 Tablespoons per load.

I've used this for over a year now and love it. The awful smell in my front loader is gone too. You can add essential oils if you'd like a scent, but I like it the way it is.

I only use vinegar for fabric softener. Fabric softener and softener sheets were the first things we realized DH was allergic to.
