OK, friends, we need to figure out what is going on here, because there are now a flock of "DIY disinffectant" solutions just like there are DIY masks.   The sprayers mostly are ionizers which use electrical current to create some ozone in the water and call it "ionized water."   While bleach is approved, these homemade salt, vinegar, and ionized water combinations are not.  Will this stuff deliver the lipoid damaging punch needed for this virus?

WACO FIREFIGHTERS PRODUCING DISINFECTANT SOLUTION TO PROTECT FIRST RESPONDERS FROM COVID-19
Tags: us_TX, industrial, discovery, environmental, bleach

A mixture of salt and water with a splash of vinegar and a jolt of electrochemical activation is supplying Waco firefighters with a safe but powerful disinfectant as they work to keep their equipment and quarters free of COVID-19.

Crews at Waco Fire Station No. 11, where the department=E2=80™s hazardous materials unit is housed, have also developed a new spray system for the disinfectant using their air tanks and other common firehouse equipment. Their formula for homemade hypochlorous acid paired with the spray system lets them kill viruses, bacteria and fungus on gear, trucks and high-use firehouse areas in 60 seconds without the need to wipe everything down afterward.

"For lack of a better term, we are the science nerds at Station 11, you know the hazmat crew. Because there is a lot of chemistry that goes into working hazmat calls, we knew we could do something during this time," said Waco fire Lt. Philip Burnett, who works at Station No. 11. "The mixture is basically water, salt and we have to put vinegar in it to lower the pH level to make it neutral, then basically =E2=80=98cook' it by putting electricity to it to make the acid with a kill-rate higher than bleach."
