Confused about hard water solutions. What's best?

P PoonamVerma 1 month ago ✓ Best Answer

Water softener changed my life. No more spots on dishes.

A AjaySingh 1 month ago

Expensive though.

S SiddharthJain 1 month ago

Seriously considering one.

D DeepakChopra 1 month ago

Scale inhibitors help, but not as much as a softener.

S SiddharthJain 1 month ago

True.
