Let’s start with the ingredients:
- ½ Cup Washing Soda
- ½ Cup Hydrogen Peroxide
Once mixed together the hydrogen peroxide and washing soda only remain effective for up to 6 hours. If it sits around, it will loose its potency.
So what I do is leave the two ingredients separated in my laundry room and add them directly to a load of laundry. For maximum effectiveness you need to let the clothes soak in the solution for an hour or two.
You can also mix the washing soda and hydrogen peroxide directly on the clothing for spot treatment and then throw them in the wash. I would only use about a teaspoon of each depending on the size of the stop you are treating.
