mould on seatblets after storage

[M3DEV]

The wifes BMW 1 series is stored over the winter (3-4 months)as we go to Spain to avoid the UK weather.
Car sits in a reasonably dry garage in a Carcoon, with windows open.
However when taken out of the Carcoon, the seat belts, steering wheel and parts of the seats have some fungle spores, the seat belts partucularly bad.
I wash and treat with interior shampoo, but this comes back each year.
Is there something I can treat the areas with that will not damage the upolstery?
Thanks

Thanks, can the Dettol be used on black fabric seats without bleaching them though?
