After trying EdFred products at home, I thought it might make a big difference in our exhibit "Water Ways". Typically, this exhibit is running constantly for 6 hours a day, 7 days a week. Although the water is filtered and treated in a number of ways, this doesn't stop the build-up of lime scale on our clear acrylics and Corian. The Shower Stall and Tile Cleaner worked perfectly. I don't think the acrylic has looked this good in over a decade.
Other employees had tried CLR with some success in the past, but nothing close to these results. Where hard scrubbing and polishing was necessary with other products, it only took a few light passes with a damp rag to remove the coarsest limescale. The Exhibits Department has now added EdFred products to our routine maintenance plans at the Children's Discovery Museum of San Jose.
