Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface. Latent prints can be found on a variety of surfaces; however, they are not readily visible and detection often requires the use of fingerprint powders, chemical reagents or alternate light sources.

In criminal investigations fingerprints are one of the oldest and most common types of physical evidence found at a crime scene. A fingerprint is simply defined as friction ridge detail of the hands and the feet. The friction ridges serve two basic purposes. First they allow us to grip and hold on to various surfaces.

The term mirror twin is used to describe a type of identical, or monozygotic, twin pairing in which the twins are matched as if they’re looking into a mirror — with defining characteristics like birthmarks, dominant hands, or other features on opposite sides.

Adermatoglyphia is an extremely rare genetic disorder that prevents the development of fingerprints. Five extended families worldwide are known to be affected by this condition.

Prints from different glove types Lined leather gloves may leave a print that is as unique as a human fingerprint. When discovered by authorities, latent fingerprints may also be recovered from the inside of these gloves.

Mix rubbing alcohol and water in a one-to-one ratio and use it to clean the DVD to remove fingerprints or other oily residue. Rubbing alcohol works well because it is mild and evaporates quickly without leaving a residue. Rub the disk with a little of the solution and let it dry.

Luckily, acetone works great for removing fingerprints from polymer clay. The acetone found in nail polish removers may not be strong enough for removing fingerprints. Your best bet would be to find 100% acetone in automotive finishing departments or even some paint stores.

TL;DR Does acetone have any effect on your fingerprints? You will be fine 🙂 It’s pretty hard to change your fingerprints. The acetone won’t have that kind of effect.

If you want to temporarily obscure or cover up your finger and palm prints you can use a variety of materials such as superglue, fingernail polish, varnish, paint, etc. Just apply to your skin, let dry, and the ridge detail in your skin will be disguised until the material wears off.

Nail polish remover isn’t compatible with polymer. Try sanding or using a bit of rubbing alcohol. I have some friends who do better than me, and sculpt $3000 polymer clay dolls. All of us pros use pure acetone to ‘sand’ and smooth our sculptures.
