Do you have a day or two when you are not going to be in your RV? Throw an Ozone machine in your camper and you will soon realize why this is such an amazing shot. How this little beauty works is that is creates Ozone. This ozone not only counteracts the green house gasses that were released from your aeresol cans in this room, it also kills the, um... unique, smells that have found their home in your powder room.
You are going to want to give the RV a day or two to let the machine fully work it's magic and be extra sure to let fresh air in before you move back in but the work will be worth it. Many ozone machines also come with AC/DC adaptor for wherever your sensitive nose may lead you.
