* ''WesternAnimation/Castlevania2017'': The people of Gresit are under assault by Dracula's army of [[OurDemonsAreDifferent night-creatures]], and powerless to fight them off. Trevor directs them in defensive tactics and instructs them to wipe their otherwise-useless weapons with salt. This allows the civilians to kill demons in the ensuing skirmish.

* In ''VideoGame/PokemonScarletAndViolet'', the evolutionary line of Nacli, Naclstack and Garganacl are [[RockMonster living rock salt creatures]]. They are the only Pokémon that can possess the Purifying Salt ability, which protects them from StatusEffects and halves the damage dealt to them by Ghost-type moves. Their signature move, Salt Cure, deals DamageOverTime that is doubled against Steel-type and Water-type Pokémon.

* ''Wiki/SCPFoundation'': [[http://scp-wiki.net/scp-612 SCP-612 ("Aggressive Cable")]]. A solution of aqueous sodium chloride (a.k.a. salt water) stuns SCP-612 and renders it temporarily inert. {{Justified|Trope}}, as high-saline water has greater conductivity than pure water, and thus would be better at neutralizing an entirely-electric lifeform.

* {{Inverted}} in ''VideoGame/LegendsOfRuneterra'', where the Grey Legion adds iodine salt into the bloodstream of their fallen allies. The purpose of the salt is to drive the risen warrior completely mad with pain as they are brought back through hemomancy, making them efficient killing machines.

-->'''TheCaptain:''' Mayday! This is Condiment Freighter 709, we're low on fuel and dumping part of our cargo! Stand by the jettison pepper. No, make it the salt!

* The zombies in ''Franchise/OnePiece'' are weak to being fed by salt (as well as getting immolated or falling into the ocean). This is because [[OurZombiesAreDifferent the zombies are powered by shadows]] that [[CastingAShadow Gecko Moria]] has stolen from other people. Since Moria's source of power is a Devil Fruit (like many other people in the verse), one of the weaknesses of Devil Fruit users is the sea itself, and salt mainly comes from the sea... You get the idea. Though salt doesn't counteract any other Devil Fruit power.

* ''Film/Warlock1991''. The title BigBad is killed by having saltwater injected into him (apparently witches are harmed by salt). In the final scene the heroine buries the Grand Grimoire in the middle of the Bonneville Salt Flats where other witches will presumably be unable to retrieve it.

* ''Film/{{Warlock}}''. The title BigBad is killed by having salt water injected into him (apparently witches are harmed by salt). In the final scene the heroine buries the Grand Grimoire in the middle of the Bonneville Salt Flats where other witches will presumably be unable to retrieve it.

* Arataka Reigen of ''Manga/MobPsycho100'' often tosses out salt as a way of exorcising spirits. However, because he uses regular tablesalt that hasn't been blessed, it's completely useless.

* ''Series/UltramanMebius'' has an episode involving the invasion of the Serpent Aliens, whose extremely high HealingFactor no-sells all of Mebius' attacks. However, Team GUYS analyzed that the Serpent Aliens' body structure are based on slugs and are therefore weak against salt, at which point they end up assisting Mebius by launching a pair of salt-loaded missiles on Alient Serpent. It works, the salt greatly weakens the Serpent Aliens allowing Mebius to eliminate them with ease.

* Lagoon creatures, a recurring FishPeople enemy in ''VideoGame/MonsterHunterPC'', is ''fatally'' allergic to salt, where a single whiff will make them shrivel before petrifying to rock.

->''"I want salt over here, as much as you can find! Everyone with a sword wipes their blades in the salt! ... SALT KILLS DEMONS! Don't forget. Spread the word!"''

Salt can cause pain, as demonstrated by the experience of "rubbing salt in the wound," or by the way it kills pests like worms or slugs on contact. This, combined with the idea that HolyBurnsEvil, might inspire this trope.

* In ''WEsternAnimation/SpriteFright'', the sprites are harmed by salt. [[spoiler:When Ellie ends up back at the campground, the salted snack foods the other campers brought allow her to fight back.]]

* Discussed in ''[[https://www.fanfiction.net/s/13139211/1/Lady-Lucks-Favor Lady Luck's Favor]]'', when WesternAnimation/DannyPhantom mentions that salt warding off evil spirits is a myth.

* ''Webcomic/CritterCoven'': Florence uses a bag of all-natural sea salt to make a protective circle when they try contacting a ghost, but doesn't have enough to make it wide enough [[http://crittercoven.com/comic/chapter-2-page-36/ for all of them]]. [[spoiler:And then the possibly-supernatural wind goes and breaks the circle anyways.]]

* In ''WesternAnimation/TotallySpies'', saltwater is used twice to melt Tim Scam's [[BlobMonster blob clones]] and to corrode amnesia-inducing bracelets.

** In the episode, "Grandma's Dead", Mac Duff, Elmyra's father, spends the whole day trying to make drinking water from desalinized tears. However, towards the end of the episode, when he tries to serve it to the guests at the funeral for Jan Brady, one of Elmyra's pet hamsters, it tastes terrible and they spit it out on the lawn. After the guests leave, Mac discovers his latest experiment will make a good slug repellant.
* In the episode of ''WesternAnimation/TheSimpsons'' "Skinner's Sense of Snow", Springfield Elementary gets snowed in, and is eventually saved by a salt silo collapsing nearby. Although this creates a different problem of corroding Homer's car so badly that the fumes start leaking inside.
* ''WesternAnimation/AdventureTime'':
** Snorlock (a slug that thinks he's a snail) is first threatened, then later attacked, with a few grains of salt. This falls under LogicalWeakness as slugs and snails really are vulnerable to salt, though the damage a single grain does is somewhat exaggerated.
** Jake's brother Jermaine uses special salt to keep away demons trying to get to the items his father has stolen from them. Since he doesn't use the salt for anything else, he has become used to eating bland food, so he's delighted when Jake makes him a meal seasoned from salt... until he discovers that Jake took the salt from the circle that keeps the demons from entering, leaving enough room for one of them to go in.
* In the ''WesternAnimation/DarkwingDuck'' episode, "[[Recap/DarkwingDuckS1E8ComicBookCapers Comic Book Capers]]", Gosalyn tries to improve Darkwing's story by adding a [[AttackOfThe50FootWhatever Giant Slug Monster]] from Mars. Darkwing defeats the monster by loading his gun with salt.
* ''WesternAnimation/CampLakebottom'': In the "Mindsuckers From the Depths" episode, a huge leech attaches itself to Squirt's skull and starts controlling him to create a rocket that would spread his fellow PuppeteerParasite leeches to TakeOverTheWorld. The leeches are defeated when [=McGee=] puts salt in the rocket instead and the resultant storm of salt causes the leeches to shrivel up.
* In ''WesternAnimation/TeenageMutantNinjaTurtles2012'', Donnie and April stop a giant worm by bombarding it with salt, which affects its neural system, causing it to calm down.
* In the ''WesternAnimation/ThePenguinsOfMadagascar'' episode, "The Officer X Factor", it's a very hot day at the Central Park Zoo and the Penguins are trying to get away from Officer X, who is substituting for Alice while she is on vacation. The Penguins build a flying machine from a pretzel cart, which Officer X stows away in. During their battle, they accidentally release pretzel salt into the clouds, creating a rainstorm.
* An evil troll named Spring-Heeled Jack is defeated in ''WesternAnimation/JackieChanAdventures'' by sprinkling him with salt, causing him to be TakenForGranite.
* The ''[[WesternAnimation/DragonsRidersOfBerk Dragons: Race to the Edge]]'' episode "A Grim Retreat" introduces the grimora, a dragon parasite that drives the host insane. The parasite's weakness is salt, so the riders are able to cure their dragons by luring them into the sea. This might explain why so many dragons live on small islands and even lay their eggs in saltwater.
* In the ''WesternAnimation/TeenTitansGo'' episode "The Spice Game," Robin's diet is so bland that even so much as a grain of salt chokes him. In the same episode, it's what allows him to get past the Dairy King by doing something unpredictable.

Sodium Chloride. Whether it comes from the earth or the sea, it is already the solution to so many of life's problems. It is necessary nutrient to prevent electrolyte deficiency and dehydration, especially in hot climate. Its ability to absorb water makes it lethal or repellent to many pests. It can preserve or pickle food, protecting it from time and decay. And, of course, it makes food delicious. Because it is so useful, it can be valuable: before the industrial age, salt could be worth its weight in gold. Many cultures came to regard salt as a [[AppliedPhlebotinum wonderful substance]] with restorative properties.

Salt can cause pain, as demonstrated by the experience of "rubbing salt in the wound," and by the way it kills pests like worms or slugs on contact. This, combined with the idea that HolyBurnsEvil, might inspire this trope.

This idea appears in myth and folklore around the world: salt is said to be a good weapon or repellent against TheCorruption,[[OurDemonsAreDifferent Demons]], TheFairFolk, TheUndead,[[OurVampiresAreDifferent Vampires]] and more. Overlaps with SupernaturalRepellent in this case.

Sodium Chloride. Its serves as a preservative for food, a kitchen ingredient, and as a weapon against misfortune. In fiction, salt or saltwater may be used to defeat antagonistic forces or to avert disaster.

Salt's ability to absorb water makes it lethal to many organisms. It's also a good repellent against supernatural creatures, [[OurVampiresAreDifferent vampires]] in particular.

This trope applies wherever salt is the downfall of a villain, even if indirectly.

Salt is also known to make a wound more painful; the saying "rubbing salt in the wound" is based on that.

SuperTrope of SaltTheEarth. Overlaps with SupernaturalRepellent when used to, well, repel supernatural beings. Not to be confused with any salt dissolved in a liquid solvent, although this trope is almost guaranteed to involve or result in this.
