yes, I have cleaned my roof using factory recommended Spic N Span a few times but scrubbing it does not restore elasticity, thickness, durability traits, etc., I'm thinking more about pro-active maintenance, as I do not ever want any kind of leak. Again, it's 22 years old now, and I do not plan to pay for an all new rubber roof. I've read that EPDM roofing is common on large commercial warehouses and in general seems to claim it's good for 30 years. Our roof has been baking in the southern California sun it's entire life.
And roofs on commercial buildings never get any cleaning or coating done to them.
However, roofs on RV’s may be exposed to extreme use by flexing, constant 60 mph winds, etc. I would be more concerned with any seams leaking more so than the rubber going bad and leaking. But a simple overcoat of whatever may seal that one pinhole you got on the last trip from something falling on the roof.
Good luck with your project.
