Wooden bowl turning my soap puck brown

I have a feeling that this topic has been covered before, but I cannot find the thread(s) to cover, so here goes again...

I have a Sabi wooden bowl that came with my TOBS sandalwood soap puck. I load my brush from that wooden bowl, which means both the bowl and the soap get wet. Although I do drain the bowl after use, some water / moisture stays behind, and the soap is leeching color from the bowl. I shaved off the discolored soap, but I would like a more permanent solution.

I have started to sand down the interior of the bowl, thinking that the stain or color is "skin deep" and I can sand off a thin layer and solve this issue. Is that going to work?

Any other advice deeply appreciated!

the stain is only skin deep however the wood (exotic i assume) has a colour of its own aswell. this can also stain your soap. I would look at applying a coat of varathane. or the other option is there is a clear coat with aluminumoxide in it. its what they use on hardwood floors. it adds strength and some moisture resistance.
This advise is coming from a journeyman carpenter not a great shaver (i'm still a n00b) perhaps others have better advise

I have no issue with the color of the wood, but this looks like it's just cheap stain coming out - I'll keep sanding gently if I have to, but only if that will really remove the layer of stain. My hopes? High, of course...

I put 3 coats of the Minwax Helmsnam on the inside and 2 on the outside of mine, the water rolls right off.

Helmsman or any Spar Urethane type coating. Something intended to handle water.

Sanding isn't going to solve the problem. The bowl needs to be coated.

I'm having the same issue. I honestly don't care that my soap is a different color, but should I apply some sort of coating anyway?

anyone having any skin reaction to the stain?
