Good day!!

I've searched and read on some previous posts on the topic but I haven't come across an exact case. Apologies if this has been tackled, kindly lead me to it if so.

The rainy season is on and while the briefcase is stored inside a cloth bag kept in a cabinet with louvered doors in an a/c room, I discovered the briefcase covered with molds/mildew a few days ago. Unsure about what kind of full grain (?) leather it is I had done the following:

- aired the briefcase in the shade
- exposed it in the morning sun for 1 hour
- wiped it down with a damp cloth inside and out, then air-dried
- placed a dryer sheet inside to help with smell
- washed the cloth bag

The white stuff on the outside had been removed and it physically looks fine. Some small black spots remain though and the strong moldy smell persists in and around the briefcase. Inside materials are a combination of leather, suede, and fabric. I can smell it standing 3 feet away.

I'm quite familiar with care and maintenance of smooth leather, but this type is new to me. Please advise how I can:
- further clean the case to ensure unseen mold spores are removed
- condition this kind of leather (without discoloring it) to extend its useful life
- remove the smell and bring out the true scent of leather.

Appreciate hearing your experience and what advise you can offer. Many thanks!

The briefcase is of this type...
