I think hand sanitizer works because of the alcohol.
As far as Rubbing Alcohol on the TPO it appears to be OK and did remove the globs of sap on the slide roof I wanted to clean.
I tested on some of the TPO material hanging inside the holes for the vents and didn't notice any immediate issues. Also, I found a list of compatible cleaners for the roof on the sani dumps web site and it listed alcohol as 'A" compatible. At any rate I used it on the slide roof, it cleaned the sap, I rinsed with water and have seen no ill effects.
