Got my warrenty Mavic back. In the video feed it looks like a hair in sunlight and it goes away when not pointing at the sun. How do you clean the lens and with what so there is no residue or damageing  ( meaning not scratching)? I aways fly my drone with the protective cover.

Porbably that is the issue flying it withg the cover. The cover might reflect against the sunlight. Take it off and try taking some more pictures.

Hopefully it's not scratched, in which case something like this will work.

Not the cover took it straight up once with out, same deal. I did spot a mark or the line. Don't want to to touch because i don't know what to clean it with or what product to use.

You can use the pen that was posted above and also use a LENS WIPES. I get mine from Walmart 200 in a box. I use them to clean the lens, the props and front vision sensors when I fly at high attitude and you will get all the bugs smudges.

Is in on the lens or behind the lens?

Cause when it's on the lens you could use a lens cleaning blower.
If it's behind the lens,......well that would be weird and pratically impossible.
