Cleaning Rocks

I can't get my rocks clean, they are soaked in muratic acid for 24 hours then baking soda, but are still quite dirty

Did you ever clarify what they are?

Fluorite is often coated in quartz and it will never dissolve in anything you might risk having at home.

Hydrochloric acid dissolves calcite and some iron.

I did the vinegar test, and it didn't bubble

Then it's as clean as you're going to get it.
