My wash tower wont retract. I know why. I have hard water buildup that makes chewing gum seem easy to remove. I have tried the following to get it out-
1.) Vinegar
2.) All Commercial Products
3.) CLR
4.) Goo Gone
5.) Muriatic Acid

I cleaned out the filter and it was like hard chewing gum. I have done and used everything I know of to get it out. I even tried a hard scrub brush. I can replace the wash tower no problem, but how do I get it cleaned out in there?
What do I use to cut this with? Please help me.
