Help...pre-spray made couch smell

I cleaned a brown corduroy couch today using Encapguard O2 from Bridgepoint. It's very versatile because you can use it as a prespray, Encap, bonnet, rinse, spotter, etc.

But it has an unpleasant smell so I put a little bit of de-odorizer in it but I guess it wasn't enough.

Customer called to say that the couches look good but they have a bad odor now. How can I fix this?

Thanks,
Branston
