They work against the hard water stains

Gets rid of rust and sediment

This is a great water softener salt.

Salt pellets were gray and dirty. Previous purchases the pellets were white.

Works great. And inexpnsive.

Great! Works as it should

it works and is easily opened.

This is the only water softener salt I use.

Don't buy this from Amazon. Walmart is better and cheaper.
