What is the best way to clean my Signature bag? The jacquard fabric is beginning to show soil (I am so careful, but it happens anyway). It is just the everyday accumulation on the front of my bag (from closing the flap, etc) I have a Khaki Small Flap Signature bag. I mainly just need to spot clean the front flap. I want to keep on top of it so it doesn't get really bad, I love this bag and want to use it for a long time. Here are photos of the dirt.
