There are a multitude of factors that effect how long fingerprints last.

How do you permanently remove fingerprints?
In order to truly obliterate a fingerprint, every layer of skin must be removed. An article in the Journal of Criminal Law and Criminology from 1935 recommended at least one millimeter of skin must be removed in order to ensure ridges do not regenerate.
Do fingerprints stay on everything?
Fingerprints have been developed on porous surfaces (papers, etc.) forty years and later after their deposition. On non-porous surfaces, they can also last a very long time. The nature of the matrix of the latent print will often determine whether it will survive environmental conditions.
What can hide fingerprints?
Simply lay out some silicone – say from clear selastic – like gutter guard or similar. place finger tips onto silicone while wet, allow to dry and no more finger prints until the selastic eventually rubs off – approx. 2 weeks. this gives a clear smooth finger tip leaving no prints without the need for gloves.

How long can you tell the lifetime of a latent print?
Findings were consistent throughout the course of the study. Latent print evidence remained constant and viable for one year; in fact, the longer a print remained on the tile under controlled temperature and humidity conditions, the more durable it appeared to become.
Can fingerprints be left on all surfaces?
Fingerprints can be found on practically any solid surface, including the human body. Analysts classify fingerprints into three categories according to the type of surface on which they are found and whether they are visible or not: Fingerprints on soft surfaces (such as soap, wax, wet paint, fresh caulk, etc.)
Which type of fingerprints is not readily visible?
Latent fingerprints are made of the sweat and oil on the skin's surface. This type of fingerprint is invisible to the naked eye and requires additional processing in order to be seen.
How long can fingerprints be detected?

There are a multitude of factors that effect how long fingerprints last.
Do twins have the same fingerprints?
They come from the same fertilized egg and share the same genetic blueprint. To a standard DNA test, they are indistinguishable. But any forensics expert will tell you that there is at least one surefire way to tell them apart: identical twins do not have matching fingerprints.
How deep are fingerprints?
High quality prints appear to correlate with an optimal penetration depth-between 40 and 60 microns.
Do fingerprints remain the same from birth to death?
Capturing a Fingerprint The value of latent prints rests on two scientifically accepted principles: first, no two persons possess the same friction ridge skin detail (i.e., everyone has different fingerprints) and second, barring any injury, fingerprints remain the same from birth until death (and post-mortem).
