What you'll need:
1/8 Cup of fabric softener
2 tablespoons Baking Soda
Hot tap water
Spray bottle (You can use your old Febreze bottle if it suits you)
Using a funnel, pour your fabric softener and baking soda into your spray bottle. Fill the bottle with hot tap water and shake well. Voila. You're done.
How does it work out price wise? This costs less than a quarter a bottle to make, depending on what fabric softener and baking soda brands you buy. Meanwhile, we are paying how much for a bottle of Febreze that is mostly water?
Makes ya think.
