After I bougt mine, it had to sit in storage for a month in the middle of summer. I didn't have vent covers installed yet, so I left the vents shut. Baking in the sun without ventilation really brought out the RV smell, but now that I'm living in it fulltime it's completely gone.
The cat litter box on the other hand.....
This might work with the cat box...
An alternative plan is to convert the formaldehyde gas into a harmless compound through a chemical reaction with ammonia gas. We haven't heard of this one before, but it may be worth a try. The theory works this way: formaldehyde and ammonia are similar in their chemical makeup. When these two gasses are combined, the resulting product is water and a harmless compound called an imine.
In practice, place open containers (bowls or pans) of household ammonia into a closed RV and leave them unattended for three days. One web site claims this will effectively neutralize the formaldehyde gas. They recommend the use of lemon scented ammonia--probably for reasons pleasing to the nose. Whether it would work to try the "cooking" process at the same time isn't clear.
