The owners manual-----------
I use the same soap that I use on the outside (with WARM water) in a bucket with 1/4 cup of bleach. Apply with a brush on a pole that you use to clean the outside. Apply to bottom of awning, roll awning up let sit for about 1/2 hour unroll, scrub again with the soapy solution. Rinse. Let dry, roll up.
This is a procedure I use.
