Yellow Aging Stains

[danag]

I would like to use my old christening gown for my daughter but it is a yellowish color now. How can I clean it, it is a combination of cotton and satin???

I've heard that bicarbonate of soda is meant to be good for getting yellow colours out of clothes...I've never used it before though...You could try dying it white or using one of those brightners in the laundry?  Maybe ask someone who knows about those fabrics first though as you wouldn't want to ruin it.

something as special as this needs specialist care. A dry cleaner should be able to help
