Cleaning old fish tank ornaments?

So this is pretty self explanatory but I have a bunch of old stuff that used to be in fish tanks (or axolotl tank really) and I was wanting to clean them up to use for a future snake if possible? A few things were actually reptile hides that I used in the tank at some point.

Is there any way to safely clean these things? I'm not sure if I should just use some diluted bleach mixture or rubbing alcohol and then rinse it?

Bleach should do it, just rinse well. Also don't use any décor that has a completely-encircled access hole in it, or your snake can get stuck if it comes partway out and then tries to go back in.

that's a good point! thank you
