At some point soon I will have to remove and clean my sct corrector, inside and out. The Fungus has got it.

I know that when I remove it I have to make sure all spacers and seals have to go back in the same place and the plate has to be orientated the same way.
But do I need to remove the secondary and its holder as well?
I'll be using Bintel solution to clean the corrector, any suggestions like rinsing the corrector first with distilled water?
thanks for any info
