Clean Daikin mini split

I DIY'ed 3 Daikin systems in my house and have been diligent about not just turning off mini, but leaving the fan on for some time to dry out coils before shutting down. I also clean filters on a regular basis. The coils look nice and clean with no noticeable mold or dirt.


But the blower, oh my, was shocked when I saw the build up on it. The unit has been in since Feb 2018 and runs most of the time here in Florida.


Searched the forum and found little on cleaning a mini or did I miss something? Looked at a bunch of You tube video's and a wide range of ways to go about it, from disassembling unit (which makes no sense to me) to buying a bag system to hang on wall and wash unit.



The owners manual only references cleaning the filters, which I do. I have only vacuumed them and never washed.



I read not to use cleaning agents on mini's then see lots of info on cleaning agents available. Which is right?



Any and all input, thoughts, ideas, suggestions, and wise cracks greatly appreciated.


Daikin, 12K 15 Seer model # FTXN12NMVJU This is the first unit installed and is the workhorse of the 3 running most of the time, the other 2 are only used as needed so not so much build up on them yet.

 

On the units we have had to clean you have to remove the coil to pull the blower. Yours might be different.
