Never use oxygen bleach and chlorine bleach together. They can react together but also IIRC Launderess explained that they work against eachother so in the end you get less bleach effect instead of more.
Why did we use oxi-clean and bleach together? I guess because we thought they both helped increased cleaning. Never saw Laundress's post. Wish I had. I only buy Tide HE Original and Regular Clorox Bleach.
Man, I have learned so much from this Forum.
