BLUE TONGUE SKINKS

I’ve collected some shale, limestone, and a bit of quartz for use my terrarium. I intend to use the whole 10% bleach solution thing to clean them, and then give them a good scrubbing with ZooMed’s Wipe Out reptile cleaner. Is that overboard, too little, will it cause some kind of chemical reaction and make them unsafe?

You should be fine with the bleach solution/cleaner combo - from what I can tell those rocks aren't porous (covered in tiny holes where bugs/bacteria can live) so they are much easier to disinfect. I used quite porous rocks in my vivarium so I had to leave them in basically boiling water to flush out any unwanted passengers before giving them a thorough clean.

Thanks!
