We have a through-the-wall AC unit in one room. There's a smell coming from it. I think it smells like gym socks, the wife thinks it has that allergy sneeze smell. The evaporator looks clean but it's definitely the source of the smell. I see products for car evaporators and products that require soaking or spraying the evaporator. Are those my only choices? Is there something I can use in situ that doesn't require buckets of liquid? How about spraying with Oxi Clean solution?

Thanks,
