Cat Urine Smell

A neighbors cat has come and peed on the door that leads from my bedroom out to the balcony, can anyone tell me how to remove the smell?
The door frame is wooden and the balcony is timber slats, I’m not able to take a hose up there but can scrub it with anything.

Thanks.

go to pet co/ pet smart or other pet store and buy an oder remover or scrub it with vinegar and baking soda, let it sit for a while and rinse with a container of water and repeat…the smell may dissipate on its own with time and it will take a long time to do so…..
