I "wash" ALL batiks in my pure white kitchen dish pan and ALMOST ALL OF THEM BLEED. Some more than others. I only buy batiks from quilt shops and not the cheap, poorly woven batiks - I am talking about tightly woven, quality batiks. I do hand wash with just a drop of liquid soap to dislodge any loose dyes. I wash in lukewarm water and rinse in cool water until the water runs clear. I did have to throw away at least two pieces that never did stop bleeding. Looked like an octopus squirting out his ink. It was a bright blue piece of fabric.
