We were asked: “Can you lighten a faux fur with hydrogen peroxide”.
You can guess the answer: try it out on a sample first or on piece you won’t see. However to be honest I don’t think it would work on most faux furs.
Hydrogen peroxide is a relatively weak bleach. Typically it is used on natural materials like human hair or linen. Faux furs or fake furs are normally synthetic.
It depends on what exactly the faux fur is made out of, this could be a variety of compounds. It might work on one or two compunds but I doubt it will have much of an effect on most.
