>>11466612university custodian here, 70% alcohol is barely sufficient,
>>11467864 is just drying out his hands because the virus is already on his phone and everything he touches because you can't just spray alcohol on everything without ruining it. What you can spray on everything without damaging it is ionized water, but good luck finding a system that makes it right now. Ion water has a 30 second kill time for covid.
Some other things that kill it are 2% bleach water and 0.5% hydrogen peroxide, with a 1 minute and 5 minute kill time respectively. High heat kills it, so you can put clothes in the dryer to disinfect them, I'd give that a 10 minute kill time just because that's how long you boil water to make it safe.
If you really want to disinfect everything in your house, go find a business that has a water ionization system and make friends with the janitor and have him fill you up a gallon jug. Be aware it only holds its charge for a short time, like 4-12 hours depending on the system.
