Good questions...& thank you for reading the labels.
I have used F10, Nolvasan & generic chlorhexidine* (*what I'm currently using) to clean cages over the
years...all work well & are safe when diluted as directed. The nice thing about them all is that you spray & wipe the cage, no rinsing needed. IMO if you have only
one snake (& btw, I have 16 currently, all long-term pets), F10 is pricey & probably "over-kill" for your needs, but it's still a good product, since you already have it.
Nolvasan is also pricey, only sold by the gallon (I think) & normally used by vets & farm operations. Generic chlorhexidine is pretty much the same stuff as Nolvasan
but way cheaper....often sold in feed stores, & you can buy a smaller bottle of it instead of a gallon. (it's also an ingredient in mouthwash for humans)
I think there is a version of F10 that has soap/detergent added for extra washing power. You don't need it. If you have feces smeared in cage, wipe off first with
a bit of dish soap/water (on a moist paper towel), then use the F10 (or other) for disinfection. No disinfectant (even bleach) disinfects that well in the presence of
organic debris, & for best results you need to let it sit wet for the recommended amount of time. Cage should be dry before snake & furnishings are put back in.
If you only spray on a disinfectant like F10 & let it air dry, it will likely leave spots (they'll show up more on the glass, of course).
BTW, I've also raised my own rodents for many years, & have used the same disinfectants on their cages too. F10 is the most recent on the market, fyi.
