I went to Home Depot yesterday and found Industrial Strength 409. It is in a white bottle with bright blue lettering. It works great on soap scum if you can't find your other product. It's not vile smelling like a lot of powerful cleaning agents.

Hi, I don't know how to paste sites but I did Google your product and came up with this:
Shower Power Bathroom Cleaner Shower Power is the best bathroom cleaner for soap scum, mineral deposits, rust & hard water stains. It penetrates and dissolves soap scum, ground-in dirt and grime, www.buyshowerpower.com
I just copied what Google gave me. Hope this helps! And if this is an absolutely wonderful product, I hope you'll post all of the wonderful things it does and the price!
