Here is what I wrote recently on here - but like "stillclock" - I think that I would not have used the hot water - just lukewarm water:
I started buying batik fat quarters about a year ago for a pattern - then found another pattern, so decided to buy 1/2 yards - then decided that I really liked the batiks - so graduated to yards. I read so much on here about the batiks bleeding that I decided to see if they did - and boy, did they. I have a pure white dish pan in my kitchen sink and one day it was empty and clean - so I put a drop or two of liquid detergent in the pan with just a little bit of water and gently swished around the fabric - I would then rinse until the water was clear - sometimes it took many, many rinses to become clear. I laid them on big thick towels and rolled them up and then put the fabric over a clothes line that I had my DH to put up in my living room. It did not take them very long to air dry and they did not wrinkle very much either. I would say that a good 1/2 of them did bleed. I actually had to throw away two of them as they never did stop bleeding.
