I wouldn’t. You risk paint loss and insert decal lifting.
If you want your Mylar to shine, grab a 3M headlight restore kit (the kind that fits on a drill). Skip the first sanding step, and go right to the second step and third step. Only use the kit on mylared areas though. You’ll tear right through the paint otherwise.
To clean everything else, I prefer naphtha and rags. It’s gentle and non-abrasive. Follow up with a quality carnauba wax of your choice.
Yellowed cloud toppers are common. Originally white, they yellow with age. There are threads on people restoring them. They basically tape off the decals, and spraypaint it white again.
Blue toppers are aftermarket, and they look bad, in my opinion. When was the last time you saw a blue cloud? I have no experience in the lightning mod, so I can’t help you there.
As for the wear around the spinners, yours doesn’t look too bad. I’d just wax it and forget about it. You can get a decal from pinball center, like Axl mentioned, but they don’t ship to the United States anymore.
Hope this helps!
