How do I clean an AT220 trap?

One of the two AT220 traps on our property has had a problem dispensing mayonnaise, because the mayonnaise has become clogged with animal fur at the point just above the long piece of tape that hangs down from the trap.

There seems to be a little open basin at that point.

It is a pain cleaning this out - took ages and wasn’t easy. I detached the trap and carefully cleaned with a kitchen knife, toothbrush, soft cloth and soapy water. Any good advice on safely and effectively cleaning the traps generally? They end up looking pretty heinous after 12 months or so.
