BMW F30 AC Evaporator Cleaning

My AC started to smell a bit. While AC is on, nothing stinks. But after turning it off and the fan is still blowing, it smells like a swamp. So I decided to clean the AC evaporator. Usually that&the source of swampy smells, apart from cabin air filter (which I also changed). I used AC cleaning foam. It&odorless after application, so it doesn&just mask the smells. Looks like it worked, at least for now.
