In the comics he can break the spell by just telling people that knew him before who he is. They just suddenly remember everything. I always thought that was a cheap way to retcon who knows his identity. I like this better.

Also, in the comics, Hulk remembers who Spidey is because he wasn’t present when the spell was cast, or something like that, it’s been a while. I think they alluded to that when Hulk stopped beating on Peter when he lost the mask.
