Yep. I’ve used walnut before and it comes out quite nicely usually
You can buy very inexpensive blasters that shoot baking soda. I’ve never personally used one but have seen videos. They seem like a potentially good solution for a seldomly needed tool.

 

A bit cleaner

I tried sanding them with 600 grit but I’m scared to ruin it

 

Placed them in just to see



Intake 1




Intake 2


Intake 3 still needs work



Intake 4 a bit dirty still

 

A major improvement there. well done.
