You will need to care for this painting a little differently than a varnished oil painting or glass covered print. Since there is wax mixed with the painting, please be sure to hang the painting away from any strong heat source such as over a fireplace or near a heat stove as the wax may melt and ruin the painting.
The painting has been sealed with a clear, top layer of wax that has been buffed into a soft sheen. After some time, this sheen may dull a bit from dust and impurities in the air. To bring it back, simply buff the painting with a soft rag or a very soft brush (like a shoe polishing brush).
