My mantra is that anything is dishwasher safe if you care little enough about it.

I put my unfinished wooden cooking utinsels through the dishwasher literally every day. They’ve been fine for 10+ years

Hmm, have you actually used wood? I've been using it for decades.

This happens after years of use ... buy a new one? They're like 1 dollar. Lol.

Food-safe wood conditioner (or just beeswax, or coconut oil, etc.) is basically free, and you should be taking care of everything wooden in the kitchen on a semi-regular basis. If your wooden cookware is degrading, I'd be more worried about the state of your wooden cutting boards.

One thing that's helped me is to every-so-often oil my wood utensils the same way I oil my wood cutting board. It's helps protect the wood and retain moisture so it doesn't crack. Also, at least some (if not all) woods have anti-microbial properties.

Wood is quite antimicrobial. You can look at studies on plastic/silicon cutting boards vs wood for a bit more peace of mind.

I put my wood cooking spoons in the dishwasher. They're the cheap kind and now they're quite bleached but they still work.
