Help - second hand sofa smells

[WickedElpheba]

We bought a really nice leather sofa from an antique shop and once I got it home I realised it was covered in pet hair under the cushions and it smells (think it's from a smoking house). It's making me feel sick. I've wiped it down with a damp cloth, used zoflora spray on the fabric bits under and around the cushions (not the leather), hoovered it especially inside... it still has a smell. What can I do to give it a good clean?

I am sensitive to smells so it's probably not filthy but I need to make it feel cleaner.

There's also a bit of emulsion on one arm I need to try to remove... kind of regretting the purchase!

I would wash it with glycerine saddle soap.

Thanks @BarnacleBeasley I was thinking of going that

is there a brand you'd recommend or are they all the same?

I don't know, I'm afraid - I don't ride so I only use it to look after my leather shoes and bags, so I have the same bar of Belvoir saddle soap I've had for years. You could try posting on the 'tack room' topic so horsey people can give you recommendations.

Is the smell in the filling of the cushions rather than the leather?

I'm not sure

it's not super strong but it's just a slight emanation

it would make sense that the smell has penetrated...

Ive febreezed the fabric cushions
