Spray it on, wait 10-15m for it to do its thing, then use a fairly strong setting on your garden sprayer to blast & flush the debris out (but not so strong as to bend the fins). You might need to do multiple cycles of this if you've got some thick debris caking going on. Try to get a look at the inside of the fins (where the fan is) - the bottom's usually the worst part because that's where water usually splashes up to help cooling.
1 can should be good for at least 2 or 3 cleanings of a window AC unit.

Have used in the past, usually just once a year, average outside unit will take between 2 and 3 cans
The evaporator is the indoor coil inside your air handler. This should be fairly clean if you change your air filter regularly, but they do occasionally develop mold if they don't dry out sufficiently (or it's a unit that runs continuously). Cleaning this will help with air quality and maybe efficiency. You're not going to hit this with a garden hose, but some people use a garden sprayer to rinse or even to spray cleaner (which you can buy as a concentrate instead of this can if you're going this route). These coils are also where you have condensation that can rinse the coil, so it's less import to rinse the cleaner. This cleaner is designed to not require rinsing per the manufacturer.
The condenser lives outside, so there is no filter and it's susceptible to dirt/pollen/leaves from the environment and tends to get much dirtier. There is no condensation here and a lot more dirt, so rinsing is more beneficial. It's also easier to get out your garden hose to do so.
This cleaner can be used for both evaporator and/or condenser coils. Not sure if it's approved for car use, but there are similar ones designed specifically for cars. Not sure what the difference would be though.

You can do it the lazy way and get half-baked results, or you can put in a tiny bit more effort using a hose and get it properly clean. If you're spending money on a product, might as well ensure you get good results with it eh?
Do some places really charge like $40 for this can elsewhere?
