Hi~
Just tried the Calgon method -- and it works. Considering that our blank tank is only a few months old, I was shocked at the results. And the Calgon/Detergent did a great job on the grey tank(s) also. I'm sold.
And hey....if you can't find the Calgon Water Softener and do decide to go with the Calgon Bath products, it's okay. After all, isn't you're Montana worth it
. At least on of us is getting a nice soak
