With Magura brakes you definitely want to lube the pistons with the mineral oil after cleaning. Otherwise they can dry out and stick worse than before you cleaned them. Learnt it the hard way.
Also it would be great to find an alternative to q-tips. I use them too but it is sometimes hard to get to the back of the piston. I have heard cleaning string recommended but haven’t found any yet.
