How does Superman clean his suit?
In this example Sheldon says that Superman must clean his suit by flying into the sun, burning all dirt of his clothes while not harming the indestructible Superman, which would work for most continuities. But within the AllStar Superman series, Superman actually got mortally sick after getting too close to the sun, his body not being able to absorb so much energy, slowly decaying until his death. While before he dies he would be his strongest ever.
