I have a light in my kitchen that Im guessing is flourescent. It is very similar to this http://cheaperlights.com/catalog/popup_image.php/pID/7?osCsid=cfadb72ab0f3fd27a5cedbaeb563f5be It is in the ceiling. How do I clean it? It has to be dirty. (I have some serious nesting..lol..ive been scrubbing everything. Im 33wks preg) THANKS@
