Removed lights, begin relocating cords and lights to next (AND LAST SECTION ON X-ARM). 6/29/15 Complete hanging of lights and begin vacuuming support tubes and spraying diluted bleach/water solution on (many) soiled floor areas. Expansion bellows are excessively dirty, therefore we will do a pre-clean on these and go back over with regular cleaning. Filled 200 gallon D. I. water tank. Only able to clean 5 meters of tube after all of that.
