You can use salt for cleaning but I think bicarb of soda and plain white vinegar works better

Good question but what does rock salt do in a dishwasher?

Have never heard of this, I assume it helps clean?

I don’t have a dish washer, so I’m a bit jealous of your problem :/ My mother in law uses rock salt though. She just uses the stuff she buys in the supermarket, but you’re probably supposed to use the proper Harvey Norman stuff

I’ve never heard of this, but then, I don’t have a dishwasher….never have. But I’m reading the answers anyway, doesn’t hurt to know

I had never heard of this

I haven’t heard of this and wouldn’t do it unless the manufacturer recommended it

i have never heard of this before

Interesting question! What is the benefit of rock salt? What is the purpose? Thanks!

Ive never heard of using rock salt in a dishwasher is it a very old dish washer that you have ??

What does this do? Is it for cleaning dishes or the dishwasher itself?

Never heard of using rock salt in the dishwasher. Is it for washing the dishes or cleaning the dishwasher itself? Sounds interesting and a lot better for the environment then harsh chemicals, either way

I’ve never heard of doing this but it has inspired me to do some research!

My old dishwasher I used rock salt. Found it cheap in the reject shop or crazy Clark’s. My new one doesn’t use it though.

Can’t say I am really sure what the rock salt does? Any how bi-carb sprinkled on the bottom of the dishwasher between washes, cleans and freshens.
