I am interested in this. I wonder if it would work as well as Oxyclean. I am addicted to that stuff. The only thing I have concerns about is adding the peroxide to laundry.
You should be able to add the Peroxide safely. I use Hydrogen Peroxide to soak vintage fabrics in. It won't bleach them - and because it's not bleach... it won't turn them "yellow"... it's what they use in hospitals to get blood stains out too! It's safer on the fabric - won't descentigrate it - so that's why they recommend soaking vintage pieces in it!
