Now it’s time to do exactly the same to the lockshield valve and you should be able to tilt the radiator to remove any excess water in it. Lastly use the radiator key to close the bleed valve which should reintroduce the vacuum in the radiator. You can now remove the radiator from the wall but be careful of any sludge leaking out the radiator so it might be useful to tape some sandwich bags around each of the valve ends.
