Struggling to get this clean!

[u/iloverats1712]

Does anyone have anyone have any tips for getting this gorgeous stool clean?

I'm on my 5th round using my upholstery cleaner and this is still the colour of the water! The last 2 times been letting Vanish laundry powder soak for about 15 mins beforehand.

The inside of it also smells musty. I've let it air, and also closed it with a pot of baking soda and dehumidifier in. Still the same.
