Photo Backgrounds - Black vs. White

I'm always looking for ways to improve the quality of my photographs and recently purchased some acrylic stands as backgrounds, one in black and the other in white.  I really like the white background as the colors really pop and works beautifully in our lightbox so there are no shadows.

The black stand, however, is a whole different situation.  I have to adjust the compensation settings on my camera which is not a problem, however I found the black is like a magnet for any lint or dust and shows the slightest fingerprint or smudge.

The other problem I am having with the black background is the reflection.  While a subtle or soft reflection can be quite nice, this is anything else but.  You can see in the photograph the inside "ceiling" of the lightbox.  I will have to figure out how to work around this problem.  Any suggestions?????
