Can you use inside on a spit unit?

Yes. Can be used on the inside evaporator coil - has a self rinsing formula that will rinse off the foam during normal operation.

can this be used on a window room unit?

Yes you can. There are a bunch of youtube videos on how to do this - whether you plan to remove the unit or leave it in place, you'll find something helpful on there.

Can this product be used to clean a car evaporator core?

Yes - it works awesome for car evaporator coils

Description: "self-rinsing design: does not need to be rinsed". the can says "rinse thoroughly with at garden hose". which is it?

Evaporator coils ‘sweat’ by their design so it is self rinsing in that application. When you are using it on something other than an indoor or vehicle evaporator coil you should probably rinse it off
