I have a problem. I used Clorox® Oxi Magic Powder on a white cotton blouse. Took the stain right out. Unfortunately, I did not read the small print on the OxiMagic until after I hand washed the blouse in hot water, Tide® and Clorox® Regular-Bleach₂ with CLOROMAX®, my blouse in now a lovely shade of pale green. Any suggestions to get it back to white?
You weren’t clear about the exact way (application method, time exposure, fiber type, etc.) you used Clorox® Oxi Magic Powder in order to create the pale green.
I’m surprised if you sprayed the stain with Clorox® Oxi Magic Powder, rubbed it in, waited 3–5 minutes before washing with detergent and Clorox® Regular-Bleach₂ with CLOROMAX®, that you had a reaction to produce the green hue. The Clorox® Oxi Magic Powder is hydrogen peroxide based — there should be no reaction with any metals or fiber types.
One possibility is the Clorox® Regular-Bleach₂ with CLOROMAX®, with its sodium hypochlorite active, may have reacted with some metals in the water supply/wash water to create the color. This usually occurs in well water rather than municipal supplies. If you have a water softener system, check if it needs to be recharged.
Your best chance for removal of this type of green is probably using a rust-remover product. Summit Instant Rust Out® and Whink Rust Remover® are two such products. These can usually be found in Home Depot/Lowes or hardware stores. A word of caution: ALWAYS read the label directions and pretest the products as they should only be used on whites/colorfast colors (check on hidden color area before using).
