Stuck tap cover

[diy_chris]

On my dripping tap the metal cover you refer to above is stuck.

It is completely smooth, so there is no way to get any purchase to undo it with a tool (I also do not want to damage it).

I have tried applying WD40, but this has not helped.

Do you have any suggestions to help me remove this cover?

i take it you are referring to an (easy clean ) cover

water pump pliers if its stuck


or a rubber strap wrench

forget about not damaging it you usually do
