Mopani Wood is easy to clean and resistant to mold.

If you use a soft wood such as cedar, be aware that it can be toxic to reptiles.If you want to try a better quality wood, try one of the above links, it is easy to clean and mold resistant.

Before putting the wood back in the enclosure, let the air dry completely.Salt and vinegar are very effective cleaning agents.Don't forget to dry it completely.I don't think bleach and water is a good idea because it is very toxic if not dried completely.It takes longer to soak and two dry periods.Once in the wash to make sure it's clean.The wash only requires one dry.It's a far safer mix, if you think about it, both might be in your kitchen now.
