The disinfectant I currently use is a hospital grade multi-surface friendly disinfectant.
I was already super clean with regards to my car pre-Covid , now I’m just more so. Just checked the app where I store all my auto records and it seems like im already due for my 3rd cabin filter. I was thinking about going aftermarket charcoal (since Honda doesn’t make one) but may buy the disinfectant cabin filter if it’s not too expensive.
Plus I lucked out on the fuel pump problem as I checked my vin and no recall on my Insight (guess its a later build ‘19).
I guess aside from what I’m currently doing , I could run the car from non-circulate and spray disinfectant into the area where the car takes in air from outside (but I don’t know where that is). Ultimately, I think just spraying disinfectant into car while AC is running high and letting it circulate for a while is good.
