How long does gunpowder residue remain on a shooters hands?
Clieclieo
as long as you leave it there... otherwise it will probibly last up to 48 hours depending on what you are doing... it will come off if you wash your hands once or twice...

What does nitrates test for?
In forensics, the dermal nitrate test detects the presence of unburned gunpowder and nitrate residue on the hands of a suspect.
How does testing on gun powder residue work?
When a gun is fired, the gunpowder burns very quickly, and produces a gas that pushes the bullet out of the barrel. The remaining gas pushes out of the barrel very hard and fast (which is why guns go BANG) and leaves traces of chemicals on things close to the gun. Some of these chemicals are found in very few things other than gun powder. Chemical tests can identify those chemicals that are left on hands, clothing, etc.
Does vinegar remove gunpowder residue?
I don't know if vinegar removes gunpowder residue or not, however I wanted to respond to your question to let you know not to use vinegar to remove gunpowder residue from any metal firearm parts. Vinegar isn't a "strong" acid, however each time it is used it will dissolve some of the iron in the steel, eventually pitting it. Vinegar won't harm your skin if you want to see if it will remove residue from your hands. By "gunpowder," are you speaking of black powder or of smokeless powder? It sounds like you're talking about black powder residue. The best way to remove black powder residue from the barrel and from any other metal firearm parts is by using warm, soapy water. Of course it's very important that all washed parts are dried immediately after they are cleaned. You can use dry cleaning patches attached to a cleaning rod to dry out the barrel. To remove smokeless powder residue, which takes firing a lot of rounds to build up, use a solvent specific for removing smokeless powder residue. Most, if not all, of these solvents contain nitromethane or another nitrated organic compound. Any gun shop will carry such solvents. What shooters often believe is smokeless powder residue is actually bullet lubricant and/or lead. Therefore, if you are using lead bullets being propelled by smokeless powder, any visible residue is almost certainly some of the lubricant applied to lead bullets, and/or it is metallic lead. Again, just about any gun shop will have a solvent to remove bullet lube from a barrel. Removing lead from a barrel requires several bronze, wire, barrel brushes and plenty of elbow grease. Pure or nearly pure lead bullets will "lead" the barrel if they are fired with a velocity greater than about 800 ft/sec. If you are using lead bullets, then I recommend getting to know someone who casts bullets or purchasing cast bullets from a popular company who uses lead alloyed with tin and/or antimony (using both is normally better). Such bullets are much harder and will not lead ones barrel unless they are fired at a velocity greater than about 1200 up to 1700 ft/sec., depending on the alloy and your particular barrel. Lead bullets that are "swaged" are pure or nearly pure lead. They are made by cramming the lead into a mold; that is the lead isn't melted and, therefore, it must be relatively soft. It's better to not use such bullets unless they will be fired at less than 700 to 800 ft/sec. Finally, copper-jacketed bullets fired at high velocities, like over 2000 ft/sec., will eventually leave a visible, albeit a very thin, layer of copper in the barrel. After a while, depending on the average humidity, the copper will turn green. To ensure maximum barrel life, one should remove any copper before it oxidizes and becomes green. Once again, there are solvents available that will easily remove any copper. I believe the active ingredient in a quality copper solvent is ethylenediamine (EDA), although it may be some other nitrogen-containing chelating agent. Compounds like EDA perform two functions: 1) they catalyze the oxidation of copper using oxygen in the air; and 2) each solvent molecule forms a minimum of two bonds to each solvated copper ion (called "chelation"), which greatly increases its solubility.
How do you make glue go away?
well if you are talking about that sticky school glue.. if its on your hands simply run water across your hands and rub them in the water if you are talking about paper your going to have to rip it! other glues are different.ANS 2 - Remove glue residue from many surfaces with 'Lift-Off, Goo Gone or Goof -Off.

Will there be gun residue on your hands after firing a 22 caliber hand gun?
Most of the residue will actually be on your wrist, but yes. After firing any handgun that discharges gunpowder, some of that powder will exit through the gun's chamber and get on your hand/s, wrist, and lower arm.
What is a sentence with the word residue?
The oily residue was sent to the lab for examination.Go and wash that residue off your hands.
How do you remove gun powder from hands?

What does the Transportation Security Administration scan passenger's hands to find traces of?
Transportation Security Administration (TSA) officers may swab a passenger's hands to check for the presence of explosive residue.
How do you tell who fired a gun?
In many cases, chemicals from the gunpowder and from the primer will transfer to the hands and clothing of a shooter. This can be found in a lab test.
How do you remove gunpowder from your hands?
Use a alchohol like nail polsh remover or rubbing alcohol but if you shot someone turn yourself in!
How should you hold a handgun for maximum accuracy at the top or on the bottom with two hands?
It depends on what kind of shooting you do. Bulls-eye shooters hold the gun with one hand. Shooters that participate in practical shooting sports typically hold the gun with two. http://www.handgunsmag.com/tactics_training/HGcombatg_100206C.jpg
