Earth Corporation Thank you for viewing. Set of 5 air conditioner cleaning sprays One bottle has been opened, but it is new. I am selling it because I don't use it. This air conditioner cleaning spray is for air conditioners with automatic cleaning functions, allowing you to easily clean the inside of your air conditioner. It was stored in the underfloor storage. New and unused, but there is some dirt on the outer container. Please refrain from purchasing if you are concerned about this. Please understand that this is stored at home. Thank you for viewing.
