I have washed my purses that are made with vinyl and with cork.
I washed it on Delicate cycle with cold water, and it washed very well!
I would recommend washing in cold water, and using a color catcher (http://www.shoutitout.com/en-US/Products/Pages/shout-color-catcher.aspx) similar to this one. I have used this color catcher on a quilt my Mom made that has a white background with dark purple pieces in it and I have not had any trouble with the colors bleeding.
I would also recommend either air drying or drying in a cycle for delicates on low heat maybe with a towel in the dryer to help cushion the rolling. I did that with my purse that I washed and dried this morning. I took my purse out before it was completely dry and will let it air dry the rest of the way.
I hope this helps and again I am glad you love your purse and appreciate you as a customer.
