at all.

Spraying through the front grill is probably not doing a very good job.
You have to take it out of the case so you can flood the coil and
possible the drain pan.Â* Best done outside so you can rinse it well.

I should add, they sell anti=bacterial pads you can put in the drain pan
to help in the future. Amazon, about 10 bucks.
