There should be a panel right in front of the coil that you can remove and gain access to it. Several sheet metal screws is all that holds it in. There may be a cut out around where the refrigerant lines are. That will come off the same way.
Once inside there probably will be another panel to the inside of the coil. Remove it.
Now, use a common house hold cleaner such as 409 and spray the coils down. If you can get a hose with a spray attachment to the coils use that to wash them down. Control your spray so as not to over flow the tray. If you can’t get a hose, use a spray bottle with clean water to wash it down.
That should be all there is to it. Put everything back where you found it and install a new filter.
