Soak it - good idea. Hot, warm or cold water?
This is what I've figured out with felting in the front end. My machine is weird....it only lets you get real hot hot water on a "sanitary wash". The sanitary wash cycle is over an hour long. I set my timer for 20 minutes and then stop the washer and put it onto rinse & spin. Its the only way I can figure out how to do it, and its been successful for 5 purse (4 of them my 15 year old DD did - she has to have a different purse for every outfit, ya know). She is currently working on her 5th.
