My sons make all our Homemade Laundry Detergent so this is a perfect and inexpensive addition to the mix.
Things you will need:
A box of coarse Sea Salt ($1.09) at Wal-mart or grocery store
20-30 drops Essential Oil(about $2.00) (any scent you like that's safe for skin, like the one's you use to make soap or air freshners) we used Orange and Japanese Lotus Blossom we already had on hand that we sometimes add to our Laundry detergent
container with lid for storage
plastic container or bucket to mix it all together in (we just used a ziploc or recycled bread bag)
a label for your container
Optional use of hand blender (we picked one up at a junk store for $2 and use it to mix our detergent with after grating the soap to make it finer)
Step 1: Step One
Place 1/2 or all of your Sea Salt in a plastic container (the first time i made this we used coarse Sea Salt from craft supply. We had left over from making bath fizzes. I wouldn't buy it to make it again because it cost a lot so we went with just Coarse Sea Salt the next time.
Step 2: Step Two
Add 20-30 drops of essential oil or if you like much lighter scent and just want the softness this can be omitted all together.
Step 3: Step three
Mix, mix, mix the salt until you can't see any part that is discolored like a wet spot. This is where we used the hand blender and gave it a couple of pulses. Not only did it mix if really well but it makes the salt even finer.
