The povidone-iodine product recommended and commonly used is “povidone-iodine solution 10%”. The iodine is here bound to the povidone complex All the dilution instructions I have seen refer to diluting this 10% concentration . This have bought 2 bottles, one from Walmart the “equate” brand and one from Amazon their “Solimo” brand.

Both list the same active ingredients and the same inactive ingredients. The Walmart “equate” brand says “Made in the USA” “Factory certified” the The Amazon “Solimo” does NOT say where it is made. I have only used the Walmart “equate

Just before indoor “shared air” exposure I 1st spray home mixed antiviral 12% xylitol in PLAIN sterile filtered water into my nose and mouth to saturation and the need to blow my nose. (a scant tsp xylitol in a 30 mL nasal pump type fine metered spray bottle such as “Snoot” brand) I use birch xylitol. Cleans nose – improves biome – reduces viral binding – antiviral activity. Plain water, not saline, seems best here per published research and confirmed in a Steve Kirsch interview with the head of Xlear, a company that produces and sells products with xylitol.

Then a few sprays of home mixed antiviral 0.5% povidone-iodine in sterile saline breathed deep as sprayed into each nostril and mouth and from a bit of a distance (aiming between the eyes at bridge of nose) a couple of sprays on to open eyes and eye area. (1 part povidone-iodine solution 10% to 19 parts saline solution note: some prefer a 1% mix 1 part povidone-iodine to 9 parts saline) Kills the damn virus. I choose more sprays, 4 into each nostril and into mouth of 0.5% (perhaps I will go to 0.6% as 1 study found more effective than 0.5%) for perhaps better wetting and coverage vs fewer sprays, ie. 2 sprays of 1%. I ignore trials started 5 days after testing positive, perhaps 10 days after infection that show no benefit. Probably offers good protection up to 3 hours. 1 study showed viral killing was gone at 4 hours. I found one hospital system mixing it, 0.5%, fresh every day out of concern that in solutions less than 1% the iodine, over time, may be released from the povidone bond. I understand this would make the iodine stronger and more irritating as free iodine dissolved out of the povidone. note: in Japan a 0.23% formulation is marketed. They were using it in the hospital 5 times over the course of the work day from just before starting work to just after finishing work. I give it a good shake before use, I mix a little at a time and use it up, if I had older solution and found it irritating I would mix up a new bottle. I have found the 0.5% very easy to use.

started out from Dr George Domb, ENT https://krcrtv.com/news/local/<wbr>redding-doctor-says-he-may-<wbr>have-a-solution-to-prevent-<wbr>transmission-of-covid-19 if it does not stay visible, refresh and rapidly click on the page as it momentarily appears. He used 1/2 tsp povidone-iodine solution 10% in a 44mL squeeze bottle of saline nasal spray. His cautions for its use (for prevention) “Do not use it if you are pregnant, breastfeeding, have hyperthyroidism, are being treated for thyroid cancer with irradiated iodine, or hypersensitive to iodine. It should not be used on children younger than 6.” I, personally, would certainly use it for all at the first sign of possible covid infection.

I wipe the spray nozzle and inside of the nozzle cap with a piece of tissue damped with a bit of bleach and clean out the spray bottle and sprayer using 70% isopropyl alcohol , spraying with the cap on loosely to rinse it out and shake out the bottle and spray out the sprayer then air dry before refilling.

For saline I use 1 part baking soda 3 parts salt which is close to the NeilMed formula for saline mix.

(by measuring a couple of NeilMed saline mix packs) to make 2 cups/16 ounces/500mL 1/4 tsp baking soda 3/4 tsp salt. I boil the water from a 500 mL bottle of filtered water for a few minutes, let it cool down then add the baking soda and salt. I let it cool till just warm because heat chemically changes baking soda.

I have not seen the version of povidone-iodine you bought used or recommended anywhere for dilution to make any covid related spray or wash.

The inactive ingredients of the recommended “povidone-iodine solution, 10%” in the 2 different brands I bought are – C12-13 Pareth-9, citric acid, disodium phosphate, glycerin, sodium hydroxide, water.

My grateful thanks to JamesK for providing the list of ingredients. I have now found a suitable product in the UK (Videne Antiseptic Solution) which has the same ingredients that he suggested, although it seems to be in short supply here. My earlier purchase (Videne Alcoholic Tincture) features Iodated Povidone (as correct) but also contains stuff like Methyl Alcohol at 30% concentration. I gather it’s more for preparation for surgical operations! Anyway, it seems to be a good thing that I checked on this Forum. Again, my thanks.
