Why is bleach used to clean up a crime scene?

351 viewsChemistryOther

I’ve seen this in multiple movies/shows where they just dumb bleach on everything. What does it actually do?
Does it erase things like finger prints?

From what I’ve seen, it just basically screws up a lot of different kinds of evidence so that it would be inaccurate. If something has been bleached then it’s harder to have an accurate read, so it can be questioned if presented as evidence.

Not an expert, just my cursory understanding.
