Eli5: Does hastily swiping off fingerprints from steering wheels, doorhandles, etc. actually prove to be effective?

I see this in various shows and movies, and it always leaves me wondering if it’s actually gonna do them any good in not getting tracked down.

If they are even smeared they are unusable. Best bet is surgical gloves or use a bleach solution as part of your cleanup. Even better is both. If you’re worried about fibers and DNA then wear one of those zip up disposable suits with the surgical gloves, shoe coverings on as you enter (wear a size larger shoe but wear extra socks as it can be noticed by weight distribution if you’re wearing larger shoes, this should resolve it though. Wear a face mask, k95 gives more room around nose and mouth. Wear a hair covering (type you’d see in surgical use) and a clear visor. Don’t be tempted to touch your face as DNA will be transferred to any surface you touch. Essentially wear barrier nursing PPE and act accordingly. Try to keep cool so sweat doesn’t drip. Wear only light underwear below the suit. Remove foot coverings leaving as not to track anything out of the house. Find a safe place nearby to remove all of this. Stand in a ‘rubble sack’ while removing it so any debris falls into it and isn’t left on the ground. Dress yourself standing in a separate sack so as not to get transfer from the area to your ‘clean’ clothing. Take the PPE in sack to a safe remote place and burn it. Ensure when purchasing that everything is flammable of course. Make your way home and put every item, outer clothes, underwear and shoes, in the washing machine. Ensure you put bleach in with the load in case of inadvertent transfer then wash hot. After drying donate clothes at a recycling point away from where you live. Ensure you don’t drive there and try to avoid the cameras. Most supermarkets are good for this as you can enter the car park directly to it without using the official entrance. Back at home do an empty wash with bleach and clean everywhere you have walked and touched thorough with bleach. Don’t Hoover as this will simply collect everything in an easy to find place. Bleach destroys rather than removes. Ideally you’d have access to another property not associated with you and unknown to anyone. Remember, nothing is secret if ONE person knows.

Anyway, that’s how I’d organize a surprise party for someone who was super suspicious and was a CSI..
