How do you clean sunshade/canvas attached to a frame/canopy?

We go through a general and gentle cleaning that involves the following:

• Brushing off loose dirt
• Hosing it down
• Preparing a cleaning solution of water and soap designed for canvas
• Allowing the cleaning solution to soak into the fabric/material
• Rinsing thoroughly until all soap residue is removed
• Air drying
• If stubborn stains persist, you can use diluted bleach/soap mixture for spot cleaning of mildew. For roof run-off or other similar stains, a strong de-greaser may be required
