No Hand Sanitizer? No alternatives? Peroxide kills corona. No peroxide available at Walmart? I'm probably shooting myself in the foot but if this could help:

Hydrogen Peroxide (H2O2) must be diluted for safe use. To dilute to a 3% solution use 1 part 12% food grade Hydrogen Peroxide to 3 parts distilled water. ... Warning: 12% H2O2 is a strong oxidizer — when handling, always use rubber gloves and safety glasses. KEEP OUT OF REACH OF CHILDREN.

1. Careful ! Also used to make meth. May end up on some kind of list.

2. Citric acid also kills -- and is in a number of Eco friendly products...

... that are still on the shelf because they don't have "disinfectant" prominently on the label.

Lactic acid too.

When wiping off door knobs, light switches, plastic food packaging, etc., saturate a paper towel, keep wiping your hands as you pick up items you are disinfection. Leave reside on package or surface for 15 minutes to ensure any virus present is killed, then, if you want, you can wipe with wet cloth to remove reside. I stopped bothering with the second wipe because when the product I use dries, you don't feel the residue.

Leaving 15 minutes is important. Studies I read indicate it can take that long for citric acid to kill all virus present.

4. I would guess that vinegar with some salt mixed in would kill the virus also.

The vinegar+salt expose the virus to two daily toxic chemicals for it, the Sodium Ion, and Hydrochloric Acid (in low concentration).

5. I've read and heard multiple times vinegar does not disinfect.

6. Vinegar plus table salt is a different chemical beast than just vinegar. nt

[GulfCoast66]

8. May well be. But without reading the results of a study I would not use it.

I’d mix up soap and water in a spray bottle first.

10. Yes. nt

12. Please don't spread misinformation.

What you have with vinegar plus table salt is dilute acetic acid (usually 5% by weight), sodium ions, and chloride ions. Chloride ions are much different from the element chlorine, just as sodium ions are much different from the element sodium.

That mixture would have no greater effect on anything than if they were applied separately.

Neither is recognized to have any use in killing viruses.

On edit: Now, if you can find some vinegar that is 10% acetic acid or more, then there is evidence that it can do some good.

16. Actually the mixture is sodium acetate and HCL and vinegar.

The addition is salt pushes the disassociation of the acetic acid to produce more acetate ions and hydronium ions, the result is sodium acetate and Hydrochloric acid in small amounts in the vinegar. Sodium acetate is a highly used anti-bacteria agent. I think I asked whether such a solution would work due to uncertainty whether enough HCL is produced (the ph doesn't change measurably, so the assumption should be that the amount of HCL is small).

11. Vinegar is dilute acetic acid

There is no hydrochloric acid in vinegar.

[Blue_true]

14. Adding salt to the vinegar increases the disassociation of the vinegar

into acetate ions and hydronium ions. The hydronium ions form HCL with the chlorine from the salt, while the sodium forms sodium acetate with the acetate ion. The level of HCL is small, so maybe it is not enough to kill a virus.

3. You got the dilution rate right. Also your suggestion that people wear thick latex gloves is on

target, latex gloves that people use for dish washing or car washing will work. 12% peroxide will burn skin on contact, but if people dilute very fast with running water, they will have an uncomfortable burn for around two weeks.

I work with 35% peroxide. I tried 10% for some formulation experiments and know from experience that will burn skin.

PEOPLE SHOULD NEVER MIX PEROXIDE AND CHLORINE BLEACH, NEVER, REGARDLESS OF THE CONCENTRATIONS.

7. Troll your liquor stores often to find 151 everclear. Or hell, Bacardi 151 will work.

Monday I scored 1.75 liters of 151 Everclear. Cut it at 60/40 with 100 proof vodka and I have 3 liters of sanitizer. Everclear is hard to find but 151 rum was well stocked. The Everclear has no smell but the rum will make you smell like a drunk. A very clean drunk!

I saturate a paper towel in a zippy and wipe down everything I touch. It last over a day and then I just re-saturate.

9. Forget all that, get a big bottle Dawn antimicrobial dish soap for 89 cents and a scrubby pad, wash

13. But playing mad scientist is much more fun! n/t

15. Find some white rum n/t
