There is no reason to be spraying any derailleur with cleaning solvents.

There is no difference between cleaning Di2 drivetrains and mechanical drivetrains.

This doesn't require Sheldon Brown's blessing, a PhD in environmental science or a World War III battle.

Remove the chain and clean. Wipe off the jockey wheels and front chainrings. Hose off any mud or dirt if present on the derailluers or spray with a spray bottle of water and wipe with a rag. Go at it with a Q-tip if you want. Reassemble and lube the chain. That's all.

Disassemble the jockey wheels, clean and reassemble with a drop or two of lube once per month or year or whenever you feel like it, more if you ride dirt.

That's all. No drama.
