Dear colleagues:



I am considering treatment options for a girl’s dress made of silk organza
that has many brown stains – possibly fruit juice or milk. Some of my
research suggests that dilute ammonium hydroxide is effective at removing
these stains, but I haven’t found any case studies.



I would greatly appreciate any information about the practical use of
ammonium hydroxide on silk for stain removal.



Many thanks,

Laura
