Yes, rain can remove fingerprints. The water in rain can wash away the oils and residue that make up fingerprints, making them harder to detect.
-
Other elements like humidity and even another person's fingerprints can also erase previous fingerprints. This is because fingerprints are made up of oils and residue from our skin, which can be easily wiped away by any form of moisture or friction.
-
Rain can also make fingerprints fade away more quickly. If a fingerprint is left on a surface exposed to the elements, the rain will cause the oils and residue to break down and dissipate faster.
-
The length of time a fingerprint lasts depends on the surface and the environment. For example, fingerprints left on a car during a rainy day might only last a couple of hours.
While rain can remove fingerprints, it is important to note that they can still be recovered under certain circumstances. Law enforcement uses special techniques to lift fingerprints even after they have been exposed to rain or other elements.
