question for all you window perf veterans. what is recommended (if any) cleaning procedures for installed window perf. asking for non-laminated perf. had some large 66" x 83" window perf (2 panels butt seamed) that client has had a window cleaning crew clean every 2 weeks. not sure what they use at this point but one of the window perf is coming loose. we used edge tape around the perimeter, an inch away from rubber seal, and thoroughly cleaned windows. also, just asking in general about cleaning, havent done that many and subject hasnt come up till now.
thanks in advance
