Wood is naturally anti-bacterial. It's true! Bacteria generally does not sustain life for long and does not duplicate on wood like it can on plastic. That being said, we know you will want to wipe down your toys on occasion, it's no problem. Never submerge your toys in water or allow them to be super wet for a long time though. Just use a damp cloth (not super wet), and a mild dish soap, use sparingly.
If the finish on your toy dulls over time you can simply apply a 50/50 mixture of beeswax and any food grade oil such as mineral oil, coconut oil, or our favorite organic flaxseed oil. No prep work needed, simply wipe on, let it soak in, then wipe it off and you are done! Just a note: just because a toy has lost some of it's shine over the years doesn't make it unsafe, it's ok if you don't re-apply a finish, toys get better with age!
Our teethers come natural so there is no finish to re-apply. We sand our teethers satin smooth so you can avoid any raised grain as your baby goes to town on these things! However, with prolonged use you might feel some rough spots over time. These are not dangerous, the wood is not in danger of splitting or cracking or anything like that. If you want to restore your teether to the satin smooth finish all you need to do is get some 220-400 grit sandpaper from your local hardware store and rub the teether surface a few times. You can also use a new green scrubber pad from the kitchen to sand it down. Your teether arrived pre-sanded so it won't take much effort or scrubbing on your part in the future.
