Yes, ZEP. They sell it at Walmart in the big gallon jugs. It's called ZEP calcium, rust, and lime remover in a purple and white bottle. It's the only cleaner I've ever found that works for what he's talking about on fiberglass tubs. I need to get my water softner replaced and the tub got rusty and that stuff works. Put it in a spray bottle and use a pad or brush to scrub it off. I do about a 3x3 square foot area at a time and it works great.
