Cleaning my Coleman Mach 3 A/C

Question

Ok. I have the diagram and and understand that I have to check/Clean the evaporator, condenser, pan and drains. Is it ok to use a softbrush to clean these parts or just stick with the spray from my house hose.
This is the first time I have cleaned an A/C. The RV is a 2016 and we have used the A/c a lot. This year 5 weeks in the dusty desert.
It is working fine. Just thought It is time for a little maintenance.

I don't use a brush when cleaning my AC fins .. they are prone to bending and I have found that soaking them with proper solution and gentle spray cleans fine.  Just my 02.

Just blow it out with a air gun, fast and easy and does a better job..
