So, as the title states, my 2yo son was playing in my 2015 Fit and had a blowout in the driver's seat. We tried cleaning it with dish soap & water, then enzyme cleaner (though we ran out while spraying). My wife then used a hand held Bissell carpet cleaner/vacuum. Any recommendations other than trying more enzyme cleaner?

Also, my neighbor mentioned that you can by used seats. Is that a thing? If so, where? Are they expensive?

 

Calling around to your local junk/scrap yards might yield a replacement seat from a scraped Fit. It's likely that a wrecked Fit would have blown the side airbags and damaged the seat cover.

As for cleaning the existing seat, I would probably remove it from the car so you have better access.

1. Unplug the battery negative. Wait a couple minutes.
2. Remove the plastic covers on the four seat-to-floor bolts, remove the bolts, and tilt the seat backwards to allow access to the electrical connections underneath the seat. Unclip the connections and the seat can be removed from the car.

You can also remove the cover from the seat (with the seat in or out of the car), which would allow better cleaning as well as direct access to the underlying foam which is likely... soiled.

I only have the 2009-13 Service manual. I can copy and paste from that if you're interested, but it would be worth your effort to search online for the 2015 Service manual.

 

Maybe try a specialized interior car cleaning shop?

 

the grossest thing I've ever had the kid spill in the car is a milkshake. i had good luck using a shop vac to suck it out. if you're planning on hosing the seat down, make gravity work for you and not against you by doing that with the seat out of the car and upside down. i would 100% start with removal, then cleaning, then removing any cleaner residue. otherwise, you're just pushing around the stuff you want to get rid of. depending how harsh a cleaner you use it may damage the fabric. hopefully you can find a hot sunny day after the work is done to thoroughly dry the seat until the humidity of it is zero.

if this ends up being a "deeper problem" and there is an odor, then i think by far the quickest, tho not the cheapest, solution is buying a new seat.

as a dad, i recommend saving the old seat and reinstalling it before you give the Fit to the kid to drive to high school in 2038 :P

 

If you ever replace the seat, I think you'll need to have the dealer reprogram the airbag. Not sure about that, but I think I read that somewhere in threads where people were replacing the Fit seat by another car seat (Civic seat). Might not apply for a Fit -> Fit replacement, but not sure...

 

I know this is an older thread and the pooped-on-seat has likely been long solved, however, my wife and I bought an extractor vacuum (Hoover brand) and it's been AMAZING at removing nasty from our Fit's seats. And we only had daily use in them. The vac has two buckets: one for a soap/cleaner solution (the vac came with a sample bottle of cleaner for pets grime and odors... it worked great for our Fit seats... I can imagine it would work great for kid poop) and one bucket for the extracted nasty solution (which was dark as coffee... just from years of simple daily use... wow). The results were so much better than professional upholstery cleaning we've paid for previously. And we've subsequently used the vac on spills on our carpets in the house, other furniture, the Fit's carpets, etc. Highly recommend.
