Unscrew the bottom one and the one going into the wall and remove and clean out the trap - remember not to pour it down this sink !!

Hopefully that will be enough and you won't need to undo the middle one and clean out up above it - I don't like the look of the PTFE tape used on that joint, there should not be a need for it unless it has been used to bodge something.

I have done that once, but fortunately there was a bucket to catch most of the water.

Look you don't need to remove it,  as I said we had exacyly the same bottle trap and you need to unscrew the cup shaped bit on the bottom, it may be stiff if you haven't done it before, and give it a good clean plus clean up the exposed spout. There is a plastic liner in it which seems to attract all the gunk.

The pop up waste will almost certainly be designed to unscrew, are you sure you're turning the right way?

knightstyle is right -  unscrew the cup at the very bottom of the trap, not any of the positions marked on your photo.

Good luck.
