All of our Tropical Plants go through a full cleaning process before being prepared for delivery. The leaves are usually covered in a white residue left over from the nurseries watering and fertilization programs. We brighten them right up, check for pests or any unwanted disease and then allow them to acclimate for 2-4 weeks. This time period allows for the plant to de-stress from the long journey and better survive the difficulties of living indoors. With clean leaves the plants are better able to filter out toxins and carbon dioxide from the air. This should be performed at least once a month with a soft dry cloth and weekly with a basic feather duster.
