a way to clean top soil before using?

[frogged]

Hello everyone! I'm curious if anyone could help me out. I have a question about top soil dirt. I know its okay to use it as a layer, however I am curious if anyone knows a way to clean the dirt somehow before using it? I mean to make sure it is safe for your frog? I currently only have 1 red eyed tree frog. I just wanted to see if there were ways to clean the dirt.

I use the dirt on the bottom then medium sized wood chips on top to keep the frog from sticking and he's been happy with that.

Thanks...

Cook it at 200 Celsius. If you're using the wood chips, try to feed the frog in the upper layers of your tank to avoid impaction.
