New spikes in COVID-19 cases have reinforced the importance of basic disinfecting and cleaning our homes to stop the novel coronavirus spread.But how do we know that the cleaners we have are effective in killing COVID-19 and other viruses?"One of the things that's important to know: Is there is a lot of good evidence that the coronavirus is one of the easiest types to kill?" said Texas A&M University - Corpus Christi Associate Professor of Chemistry Dr. Patrick Larkin.Yes, he said. He believes most household cleaners will destroy the virus.He said the best chemicals to use for disinfecting are, bleach, ammonia, and alcohol. However, he does warn that precautions be taken with alcohol concentrations."For example with isopropyl alcohol, you need at least a 50 percent solution; and ethanol [or ethyl] alcohol, you want at least 60 percent," he said.But, take note -- there also are guidelines for how you should clean, so it can be the most effective."CDC guidelines say you should clean the surface with soap and water first, and then apply your sanitizing or disinfectant solution," said retired Certified Industrial Hygienist Tom Samson. "Leave it on for at least one minute, and then you can rinse it off."Samson said not all household cleaners are the same, and do not have the same contact-surface time that is required. He recommends reading the labels of the cleaner you intend to use.Larkin and Samson said it is easy to make your own cleaners at home. However, be cautious about mixing chemicals, and be aware what you are cleaning with."The chemistry of mixing a chlorine-based cleaner with an ammonia-based cleaner can be deadly to those in the immediate area," said Samson. "The reaction of these two cleaners is to release chlorine products into the surrounding environment, in some cases, enough to cause severe injury or death. People need to know to get out of the area if this reaction happens and take their kids and pets with them!"Samson notes the Environmental Protection Agency also has a list of cleaners that will kill the novel coronavirus.This story originally reported by Chelsea Torres on kristv.com. 2149

NEW YORK (AP) — A federal judge in New York has ruled that Acting Department of Homeland Security Secretary Chad Wolf assumed his position unlawfully. U.S. District Judge Nicholas Garaufis's ruling invalidates Wolf’s suspension of the Deferred Action for Childhood Arrivals program, which shields young people from deportation. Wolf effectively suspended the program in July, a month after the U.S. Supreme Court ruled against President Donald Trump's efforts to end it. Garaufis wrote Saturday that DHS failed to follow an order of succession established when then-Secretary Kirstjen Nielsen resigned in April 2019. DHS did not immediately respond to a request for comment on the ruling. 696

NEW YORK CITY — Complaints of fireworks are booming in New York City.There were 1,737 calls about fireworks recorded with 311 in the first half of June, which is more than 80 times the amount in the same time period last year.Brooklyn has had more complaints than any other borough. Borough President Eric Adams doesn't want to see attempts to end the fireworks turn into "fireworks between the police and the community.""It's time for all those who call 311, who don't want heavy-handed policing, it's time to come out of your homes and talk to the young people or the people on your block who are setting fireworks off," he said.Fed up, fatigued or just fascinated, some are turning to social media to ask some form of the same question: What's up with the fireworks?Some suspect they may be shows of support for the protesters following the death of George Floyd. Others wonder whether they're simply a way of blowing off steam after being stuck inside by restrictions meant to limit the spread of the coronavirus.This story was originally published by Cristian Benavides with content from the Associated Press on WPIX in New York City. 1147

NEW YORK (AP) — Walmart said in a press release that the ammunition and firearms removed from displays at U.S. stores on Thursday was returned to the sales floor on Friday.“After civil unrest earlier this week resulted in damage to several of our stores, consistent with actions we took over the summer, we asked stores to move firearms and ammunition from the sales floor to a secure location in the back of the store in an abundance of caution," the company stated in a news release. "As the current incidents have remained geographically isolated, we have made the decision to begin returning these products to the sales floor today.”Walmart said on Thursday that it had removed ammunition and firearms from displays at U.S. stores, citing "civil unrest" in some areas. The nation's largest retailer, based in Bentonville, Arkansas, sells firearms in about half of its 4,700 stores. The discounter said the items remained available for purchase by customers. Walmart made a similar move in the wake of the police killing of George Floyd that set off sometimes violent demonstrations against police brutality and injustice against Blacks. Last year, Walmart stopped selling handgun and short-barrel rifle ammunition while requesting that customers not openly carry firearms in its stores, even where state laws allow it. The company also ended the sale of handguns in Alaska, the only state where the discounter sold them. 1432

NEW YORK, N.Y. – It’s been nearly a year since the death of Elijah McClain in Colorado, but as people across the U.S. learn of his case, more are calling for justice.In New York City, a beautiful vigil was held on Monday to honor the life of the 23-year-old man, who played violin.A crowd of musicians with string instruments gathered in Washington Square Park to play a variety of songs, like “Amazing Grace” and “We Shall Overcome.”In videos shot by Yuxi Liu, spectators with candles can be seen crowding the Washington Square Arch, where the musicians were playing.Liu says the vigil wasn’t organized like a formal event, but that’s part of what made it so special. He says there was no rehearsal and you can even see people running up late in his video.“However, that’s exact the reason why it’s beautiful,” said Liu. “People showed up only because people care. Me and bunch of other photographers showed up because we want to help document the moment.”Elijah McClain caseThere’s been renewed interest in the Elijah McClain case after nationwide protests put a spotlight on past instances of police use of force across the country.McClain died on Aug. 24, 2019, shortly after being arrested by officers with the Aurora Police Department.KMGH reports that McClain was walking home after purchasing iced tea at a convenience store when a bystander called 911 to report “a suspicious man wearing a ski mask and waving his arms.” Family says McClain wore the mask because he was anemic and got cold easily.When officers tracked McClain down, police say he began “resisting.” Body camera footage shows officers grab McClain almost immediately after attempting to stop him.As police struggled to detain McClain, an officer placed him in a "carotid hold" — a maneuver designed to limit blood flow to the brain. When McClain became unresponsive, paramedics administered a shot of ketamine "due to the level of physical force applied while restraining the subject and his agitated mental state."Police insist that paramedics were the ones who chose to administer ketamine. Paramedics say the procedure is common in the area.McClain later suffered a heart attack and died six days later.Now, the Colorado Attorney General’s Office is investigating whether criminal charges are warranted against anyone involved in McClain’s death.Click here for more on the McClain case. 2372
