I did have to soak this several times. There might be a little tiny bit of blue hiding on the quilt, but really it is so hard to see. I recently soaked a white wholecloth quilt. Very dirty, lots of spots and stains, yellowing. It turned out beautiful. I have used it a lot on redwork blocks and redwork quilts. I have not had a a problem with any of the embroidery fading. In fact right now I have a whole stack of things waiting for their turn in the soak. I always say you have to make the call yourself whether you use it on your quilt or fabric. No guarantee it would not ruin something. My decision is always based on the worst that could happen to a quilt I maybe don't feel I could live with the dirt, stain, etc.
Many years ago as my kids were growing up I used Biz in the laundry. And I used Biz on old quilts and blocks. But about 6 or 7 years ago, something happened to Biz and it was no longer the same formula. I learned the hard way. I put a 1930's pink and green quilt into a Biz soak and the pink ran all over the place. I should show you a pic, but I would have to go dig it out of the bottom of a closet. I had never had that happen before with Biz. I happened to have an older box of Biz and compared it to a new box. Different ingredients were listed on the box. So long story short, I tried a whole bunch of different products to try and find something that preformed like Biz. That is when I found Restoration. I like it a lot and use it a lot. I use it so much I had to become a dealer. You can buy it from me if you are in my area. Or direct from Engleside.
