A favorite view of Spider-Man (at least in movies and games) is of the hero web-slinging his way through the streets of New York City. But what becomes of all the web ropes that Spider-Man discards as he moves from building to building? We don't see them hanging around the city, so presumably someone removes them.

Do people collect them as souvenirs? Does Spider-Man come back later to clean up after himself? Does the city employ a group of cleaners just to remove the webs?

    Are you talking about comics, movies (which series?), or some other media? The answer and the evidence may be different depending on which you want? Sep 8, 2018 at 13:39

    In the original comics, his webs dissolve after an hour or two, which is why he never made any money from them. Sep 8, 2018 at 13:46
  • @Thunderforge Any or all is fine. The question came to me after watching a trailer for the newest Spiderman game.

    @Edlothiad Is there any canon source where it doesn't dissolve after a certain amount of time? I feel like this is the answer across all canons.

The general idea, although the exact answer varies by Universe, is that the webs dissolve after a few hours.

  • I was going for an answer which gives over the general idea because the exact answer varies greatly from universe to universe

    Perhaps you might improve it by offering some examples from a range of universes.

In the MCU,

Peter Parker's web formula dissolves after two hours (or so).

Spider-Man: (to Aaron Davis) Hey, that's gonna dissolve in two hours.
Davis: No no no no… come fix this.
Spider-Man: Two hours—you deserve that!
Spider-Man: Homecoming

In other universes,

I don't have any specific examples, but I'm not aware of any evidence that suggests any different behavior.

In the most recent movie, Spider-Man: Homecoming, there is a scene where he is interrogating the low-level criminal played by Donald Glover after sticking his hand to the car with webbing.

When Spider-Man leaves he tells him that it will dissolve in about 2 hours.
