read the link !! Yes it keeps mentioning aqua net. I do know I used to spray my moms polyester nurses uniforms to get ink out of the uniforms. Worked well, and sometimes I didn't wash then for a few days after spraying. Didn't yellow or stain. Only problem we had was the well water in Wisconsin when we lived there. It left rust on everything. Had to buy and install water conditioner system for house, then still buy special stuff and treat laundry to get rust out. May try first quilt and see how it works.
