So, how often? Monthly checks, refill when it’s low. For most households, that’s once every four to six weeks. For the forgetful (which is 90% of us), buy a bag of salt when you buy your groceries, and toss it in the garage. That way, when you finally remember, you’ll feel like a responsible adult who has their life together, even if your socks don’t match.
And if you accidentally go two months without salt? Your water won’t immediately turn into lava. It’ll just be hard. And you’ll notice every single spot on every single glass. But hey, now you know. You’re welcome, and I’m sorry about your dishes.
