A 2019 study published in the journal 'Nature' reported that nasal irrigation and gargling with salt water helps kill the viruses that cause the common cold.
A recent reanalysis (made public in April) found the same procedure is effective with coronavirus infections. The study's authors recommend gargling and nasal irrigation as a treatment option for COVID-19.
The mechanism how this works is described in a paper linked below ('Antiviral innate immune response ... intracellular hypochlorous acid levels'). The body's cells recruit negative Cl- ions from the saltwater (NaCl) solution to formulate HOCl (the active ingredient in bleach). If disinfectants like bleach are applied topically, they destroy both tissue and virus. But here, the body's' cells generate HOCl in a targeted manner *within the cell* to suppress the virus.
Gargling and nasal irrigation are simple and cheap home remedies familiar to billions worldwide. Let's do this thrice a day in our fight against COVID-19. See the 'Gargling and nasal irrigation procedure' link below for more information.
Some notes:
The official name of the procedure is "HSNIG" (Hypertonic Saline Nasal Irrigation and Gargling). But "Saltwater Infusion in Nose and Gargling" or "SING" is a memorable alternative.
The official procedure of nasal irrigation uses a cup, but an alternative is introducing pre-boiled and salted water into the nose with a teaspoon.

Johns Hopkins Center for Health Security says this has no direct effect on the virus. (link)-- tatterdemalion, Apr 07 2020 Tatterdemalion - I get your concerns. But medical professionals around the world are struggling to cope with Covid-19. Where we can assist, we should -- such as with social isolation. But this virus will come knocking on everyone's door... in second, third waves, and more. If we have a safe, scalable preemptive procedure that works, we should use it.
The John Hopkins advice you linked to is wrong. I assume its author is unaware of the research linked here, which is recent. The 'Nature' paper (1st link) showing salt irrigation and gargling procedure works is dated 2019. But its followup article (3rd link) showing that it works against Coronaviruses is brand new (pre-print was announced 5 days ago).
Below is personal communication from a professor I wrote to who backs this advice. I've also written to the JHU professor dismissive about gargling, but haven't heard back yet.
"Sonam, thank you for promoting this advice which would significantly slow the spread of Covid- 19. Johns Hopkins is a fine institution, but obviously, they are ignorant of the recently published science. That is not shocking as it generally takes 25 to 30 years for good published science to be utilized. We must keep pushing this message which has excellence science behind it. The medical professionals against it will eventually be shown to be ill-informed!" -- Bradley F. Bale, M.D., Clinical Associate Professor, Washington State University School of Medicine.-- sonam, Apr 11 2020 I'm just some dude on the internet too, which is why I'm not offering medical advice here, and neither should you.-- tatterdemalion, Apr 12 2020 //medical advice here//

// Salt water up my nose usually makes me spill even more gooey cellular stuff.
Exactly what needs to happen :) ... But it's not just what comes out that helps, but what goes in -- the salt solution. Your cells reuse the 'Cl' chloride ions to generate hypochlorous acid, using it to suppress the virus.
Quoting from the fourth link: "In cell culture models, DNA, RNA, enveloped and non- enveloped viruses are all inhibited in the presence of NaCl. [...] Here, we show that epithelial, fibroblast and hepatic cells have enhanced antiviral activity in the presence of increasing concentrations of sodium chloride (NaCl). [...] In the presence viral infection and the availability of NaCl, cells utilise the chloride ions to produce hypochlorous acid (HOCl)"
So grandma's generation was right, even thought they didn't know exactly how it worked.-- sonam, Apr 12 2020 And a greater chance for transfer of infection if gargling/ clean up procedures are not correct. Infectious spots around the sink, if viral kill isn't 100%

wjt - //if gargling/ clean up procedures are not correct...
A fair hypothetical but your concern is directly addressed by the research results: a 35% *reduction* in virus transmission to household contacts. If you look at the researcher's website, he also suggests rinsing out the mug with soap after the procedure to protect against cross- infection. Yes, you're expelling virus particles into your sink, but that means its not *in* you. And you can always clean the sink (the virus don't like soap much). This is more a problem in very dense, communal living arrangements -- like tenement or dormitories with shared bathroooms.
RayfordSteele - I agree. That this is a pre- emptive/prophylactic measure that works best at the initial stage of the infection. At later stages, I had another half-baked idea that may help with that - a oral device that emits UVC light. It could also emit a mist of warm salty air (like from an ultrasonic transducer vaporizing a saline solution) -- see last link-- sonam, Apr 14 2020 random, halfbakery
