I have been using a very similar recipe for two years. If you put a scoop of Oxi-Clean in with the whites, you will not have any grey-white clothes; my clothes come out of the washer bright white (BTW the clothes will last longer using Oxi-Clean rather than bleach).
Also, don't forget the vinegar rinse!
I would love to ask "Anonymous" a couple of questions! So if you drop back by, hope you will let me know how to contact you.
I have had mixed results with Oxi-Clean. It seemed to work better when I lived in Northern AZ in red dirt country and had harder water. Would that make a difference? Do you use the powder or liquid. Does that make a difference. When do you use vinegar in your rinse water? All the time or just when you are washing whites. I know apple cider vinegar is a great rinse for your hair. Leaves it clean and shiny! I have also used white vinegar in lots of cleaning situations.
Please share your secrets!!
