I spilled gas inside my conversion

Last week when i was on my way back from the lake i put my boats gas tank inside my cargo trailer for the way home. Apparantly it wasnt secured down well enough and tipped over and spilled 50:1 TWO STROKE mix all over my floor. I put baking soda over the spill and it sucked some of it up but the smell is still there very heavily. The bad thing is that i was just about to lay the carpet down for the conversion. Is there a way to get rid of the smell or even to seal it in. I'm open to any and all tricks
