Hey all- So I've started a cleaning project of my college's small theatre. It has no resident technical director because it is so small. It's often used as a kind of "patch and run" theatre... meaning directors and techies will come in, fix up the lighting and backstage areas for the show, then load out and leave it a mess. And since there is no technical director.. there is no one to make sure things get cleaned properly. ANYWAYS.. today was the first evening I popped in to start taking inventory and assessing what needed to be done. I was astonished to look up at the rear black border drape and see that the top half was so dirty/dusty it was a light brown. All the other curtains (travelers.. other borders) are in similar shape. What's your recommendation for cleaning them? Keep in mind, these aren't hard borders, they're black fabric curtains dead hung to rails and tracks. The borders seem to be the only truly removable ones as they are simply tied to a dead hung batten. Let me know what you think. I know this isn't a conventional issue, seeing as theatres with a TD would never let the curtains get this disgusting. Thanks again!
