Have you considered centre lock adaptors and if so, what's your reason to avoid them?
Yes I’ve used adapters. Nothing wrong with them but it makes installing slightly more faffy.
I haven’t used centerlock adapters with magura 220mm rotors. I won’t consider rotors from unknown manufacturers like sumart or other shit like that. Aside from hope vented rotors (which are too thick to work and also don’t fit the adapters), the mdr-p’s are one of the thickest rotors I know but they don’t make the 220mm in centerlock.
BCA makes a 2.4mm 6-bolt rotor which I could use with an adapter but I haven’t tried them (yet).

Cleaning pistons is good general maintenance and makes a difference in the seal longevity and helps clear up the bores of any material that might lead to corrosion build up, but I'd just go ahead and order one of the aftermarket rebuild kits on Amazon/Ali and swap the pistons and seals out. Then you'll be well able to clean the piston pockets, ensuring less likelihood of corrosion build up. Those kits work well enough and are cost effective, so if you're going to disassemble a caliper you may as well rebuild it with fresh seals and pistons. Air compressor works a peach to pop the pistons. Blow in from the hose port or caliper bleeder port and make sure to wrap the caliper in a rag prior to doing so.
What do you mean with the vent hole in the membrane?
There are vent holes in the membrane cover. The membrane can't have any holes in it.
Yeah man, I don't know what I was thinking! I have seen brakes that have little signs of fluid weeping from the vent hole in the membrane cover, and I had thought some manufacturers might have been incorporating a sort of pressure relief hole into the rubber membrane. On further consideration, I guess they all probably just had membrane failures, or weren't' tightened evenly such that fluid could work its way around to the air vent hole in the cover.

It's just water/moisture getting pushed out from above the membrane. It's normal.
Or fluid that might have gotten in there from messy bleeding or that has seeped through the membrane.
