While today’s quilting fabrics tend to be more colorfast than ever before, some colors and dyes do run, and it may not always be the ones you’d expect. Red, navy and purple are notorious, but other colors can bleed during the wash, as well. And, they may not do so until the quilt has been washed a few times.
Consequently, it’s a good idea to test fabrics for bleeding before using them. Janet Wickell has written an excellent article for The Spruce Crafts that explains how to test and what do about a fabric that bleeds (don’t use Retayne, as that may make the problem worse).
So, what did we mean by that comment indicating that some dyes may not bleed until the quilt has been washed more than once? Vicki Welsh from colorwaysbyvicki.com has studied dyes and bleeding extensively, both in commercial and hand dyed fabrics. She offered the following example:
“I recently bought a commercial purple fabric. I washed it once just to test my theory. I put in a color catcher to see if it bled in the wash. It didn’t. Then I soaked it overnight and by morning the water was DARK purple! It was eventually going to bleed during one of the washings had I not soaked that fabric because exposure to water is cumulative. “
Consequently, the standard bleeding test, as outlined in the article above from The Spruce Crafts, may not be enough to determine whether or not a fabric will bleed. When in doubt, or when choosing fabric for a special quilt, we recommend Vicki’s testing method.
This is an excellent article that provides important information about bleeding dyes. We recommend that every quilter read it.
While the article focuses specifically on washing a quilt for the first time, the same method can be used for determining whether or not a fabric will bleed and for removing excess dye from those that do.

So, back to vinegar, salt and Color Catchers. Some quilters swear by adding vinegar, salt or both to the water when washing a quilt for the first time. While both of those, along with baking soda, may help set some dyes, they won’t work on all of them. So, you’re taking a risk if you rely on those to work 100% of the time.
Color Catchers are popular because they catch and trap dye that’s released in the wash so it doesn’t settle on other parts of the quilt. They can be helpful – but only if you use enough of them and continue for several washes.
Depending on the size of the quilt and the fabrics used, you may need to use 6 or more to capture all of the dye that’s released. And, you’ll need to do that for several washes, as some dyes may not be released the first few times the quilt is washed.
If you typically give a box of Color Catchers when gifting a quilt, be sure to explain how to use them to the recipient. Or, test and pre-wash the fabric before using it (better yet, pre-soak using Vickis’ method) and avoid potential problems altogether.
