I've never found CLR to work that great on heavier deposits of mineral
buildup. What's better?

Give Lemi-Shine a try.
Available at most grocery stores on the dishwasher detergent isle.

It's basically citric acid ~$4 per pkg (10 oz)

I use it to remove & control hard water deposits in dishwashers.
And as an occasional rinise (~1 month) aid.

Be forewarned.... it will remove (over time) artwork on some glassware
or coffee cups.
More aggressive than CLR less than pool acid.
