Magura 6.1 pads seem to be pretty resilient.
Having bled my brake I was a little ham-fisted and splashed oil from the top syringe around, some got onto the pads.
Rotor was washed in HOT water and washing-up liquid, scrubbed with a brush to get inside all the cutouts etc.
Pads – I heated [with a wire through the retaining hole]them in a gas-ring flame until they were about 100C [spit test] and then heated them for about as long again . Quite a lot of smoke came off. I repeated this twice, allowing them to cool in between.
When they were cool I washed them in running water and rubbed the friction material of them together quite hard to remove any surface glaze.
I cleaned the inside of the caliper with cotton-buds and a little nail-polish remover.
I tested after in free space in case the pad was about to disintegrate. They way I see it you are supposed to buy new pads, I was resigned to doing-so, so I though I have nothing to loose.
The result was a success – braking restored. It may not work with DOT fluid, or with fancy Teflon fluid spills, but plain oil seems to come out.
I have also heard it suggested that boiling them in very detergent-y water for hours?days? might work.
Good luck.
