used neat hydrogen peroxide on cotton embroidered duvet cover -yellow stains :(

[scarletforya]

I used neat hydrogen peroxide on a white duvet cover to lift stains. It lifted the stains but left a yellow stain instead.....can I remove this somehow?

Does sunlight work on a hydrogen peroxide stain?

Try using a paste of bicarb and water - 3 parts bicarb to 1 part water - and rub in to the stain. You can also try ammonia, but bicarb and water will be much more pleasant.

You might need to repeat a few times. Then give the duvet cover a wash.

Thank you! I will try that.
