Can I leave a folding camp chair outside, and how do I clean it?

These are chairs you carry, not patio furniture, and they are meant to come back inside. Left out, polyester fades in the sun, rain collects in the seat, and a steel frame starts to mark where the finish is scratched; left out under snow, a folded chair holds water all the way to spring. Cleaning is mild soap, water and a cloth or soft brush - no pressure washer, no bleach - and the rule that matters more than any of it is to dry the chair fully in the open position before it goes into its bag. On the heated chairs, wipe rather than soak, keep water away from the connector, let everything dry before plugging anything in, and store the cable coiled loosely instead of bent tightly around a leg, which is what eventually breaks a wire. Winter storage is indoors, dry, standing or flat - not folded damp in an unheated shed.
