Me too. Rebuilt quite a few engines. But, I took an internally dusty 50mm f1.4 (Zeiss) Practika lens apart and made the mistake of assuming the iris leaves were metal and wiped them with a quick drying spirit cleaner. Turned out they were plastic, so partly dissoved and bonded together. Result, dead lens! Good job it wasn't an expensive one.
It is impossible for anything digital to sound analogue, because it isn't analogue!
