You can clean it by boiling it in vinegar, but that may not work.

If they don't work correctly, I replace them.

One of the radiators in my home doesn't seem to be putting out much
heat. It has one of those self-bleeding valves on them, and while the
others give regular loud 'hisses', this one gives a half-hearted
whistle every now and then.

I thought maybe cleaning/replacing this valve could solve the problem?
Is there any way to do this easily (without emptying the system). Oh,
and yes, both valves are all the way open.

Thanks,
