Washing in cool water is a good idea, too bad I didn't read that before I decided to go ahead and "take the plunge"!
I started by dunking the 2 burgandy bags in warm sudsy water and there was some color release into the water, but not bad at all.
Encouraged, I gave the red duffle a good looking-over and decided to wash it too. I added it to the suds with the other 2 bags and the water still just had a light redish tinge so I was encouraged to continue.
When I started rubbing the bags with a soft cloth to try and get out the dirt - that's when the water really started to turn red! My fingers were staining red too, so I had to put on rubber gloves.
The small burgandy bag seemed to bleed the most. By the time I was done the water looked like blood!
The rinse water had a lighter red color and the bags are drying now. They look okay for the moment, but they are wet so we will have to wait and see what happens.
Below are some pics of the washing process.
