Hello! Medical alcohol is 75% ethanol, which can denature bacterial proteins and thus play a role in sterilizing and killing viruses, and the effect is very rapid. The alcohol content of Blue Lizard Alcohol Disinfectant Spray is just 75%, and the trademark is a Class 5 disinfectant that can effectively inactivate viruses. I suggest you store a few bottles at home like me, but don’t store too many. Leave some for other users. You can put them in your bag when you go to work or buy groceries. You can use them anytime and anywhere, and keep them on hand at all times. All clean.
