To my recollection (corrections welcome), the covid19 virus has been reported to live on hard surfaces for 8 weeks, have an incubation period of up to 4 weeks, and live 5 weeks in vitro after confirmed infection ... if you're sanitising several times a day then that's a need for quite a long stretch of sanitiser.
Do you have sources for those figures? The ones I find are suggesting up to 2 weeks incubation (but more typically about 5 days) and surviving on some surfaces for 3 days (less for others).
