Long story, made short.
Started with new smelly luggage.
Chamber maid tried to remove smell by spraying some cleaner on it.
I sprayed a second dose of this cleaner on it (outside).

Next I placed newspaper and coffee inside the luggage. It had no
impact.
Next I bought a car freshener cardboard and placed it inside the
luggage.

Net result, the luggage and all its contents have a combined putrid
smell now.

I chucked the luggage in the garbage after removing all its contents.

How can I remove the horrible scent from all of the items that were in
the luggage?

Most of the items were clothes.
I have washed them in a machine with lots of detergent and they still
stink.

Other items include leather belts, a small travel bag for toiletries,
computer connectors/adapters, headphones etc.
