This will disinfect right? Please answer my questions!!! I have no idea and I’m so worried about corona

I’m assuming I can use this to disinfect/clean due to everything going on as it says “kills 99.9% of bacteria” right?

Also, the back of it says to disinfect you apply the full strength product on the surface, allow to sit and then wipe...is this safe to do so? On everything? My roommate told me I should just dilute it with water, but I want to make sure I actually kill everything!

Sorry, I just moved out on my own so I don’t know anything 😂 my roommate has a son that comes once every other weekend,’so I want to make sure it would be safe for him as well? Should I air out the house?

*also, it says a rinse is required for surfaces with direct contact with food...does this mean countertops? If so, how would I rinse?
