Cleaning Lennox Cased coil

I have a Lennox SLP98 furnace with a cased AC Coil (C35-36B-2F-2). I would like to clean the coil. I have opened the access panel, but am perplexed on what to do next. The side bracket on the coil cannot be removed because all of the tubing is in the way. I have seen videos where the entire coil is slid out through the front. However, my furnace exhaust pipe is cemented in, and If I cut it low enough to make room of the coil, I wouldn't have a way of reattaching the exhaust pipe. How is the AC coil cleaned in such a situation?

Coil cleaning is not a routine job.
It needs to be done if you have excessive restriction in the air flow.
If you were running the furnace-A/C with no filter.

You have an A coil there. You would need to clean the bottom.... inside the A.
That means breaking the coil from the drain tray and removing the assy from the furnace.
I'd pass on a routine cleaning. To risky to move that coil.
