I spilled fuel injector additive on my car floor. I have tried to clean up but...

[shakeel916]

...my car still smells. Help? I spilled fuel injector additive on my car floor. The additive spilled on the driver side floor. My trunk and gas levers were affected and I believe it might have spilled below the carpet (through the carpet hole). Unfortunately there is a very nasty smell and I have tried various methods to clean up but the car still smells like fuel addative. Please help!
