What is the best way to clean rocks? I just sprayed a few of them, and then put them in my tank, but I'm waiting on the rest, as they aren't as needed. How should I clean them?

A good wash in warm water with a stiff brush will be fine.

if you have a gurny (high pressure cleaner) use that, saves time scrubbing
