Mildew on Wall tent

[Douglas Hicks]

My hunting camp set-up is a 10 X 16.5 wall tent w/ a separate 10 X 12 kitchen on the front of the main wall tent. The fabric is canvas. I have a mildew stain on the front entry panel of the kitchen. How do I get it off, and keep it off? Do I use bleach, and if so what strength? Do I hose the bleach off, or leave it? The kitchen is damp, so tommorrow I'll set it up and let it dry.

Thanks in advance
