To disinfect with alcohol, it would have to have surface contact for over 30 minutes. Just an FYI.

I personally use chlorhexidine or parvosol/parv-o-way(virucidal/bacteriocidal/fungicidal) to disinfect. To clean, the tub gets put into the bathtub and washed with Dawn or Palmolive. Cleaning and disinfecting are two different things. You can't make dirt clean

And window cleaner isn't a disinfectant or anything of the sort.
