I successfully lightened foxing stains on silk with a 10% citric acid solution, followed by deionized water.  It had a tendency to over-clean the area, so precise control was necessary.  Good luck on your project!

Dear All:

 

I am researching treatment options to remove foxing stains from a linen garment. I am particularly interested in treatments that include chelators and enzymes. I would appreciate any information about textile treatments to remove foxing stains without bleaching.

 

Warm wishes,

Laura
