My car has fungus on seats, any remedies?

with craigslist or facebook market place you can find a good deal on seats in good condition well god luck. as for the seats that you have right now you may eliminate the odor for some time but problem will alway come back at you therefore I would suggest just finding a new set of seats (people junk cars all the time and in many cases cars are in great condition and you can get parts of from them)
