Etching stains after clear coating

I have had a problem with the etching soot seeping up and staining the top of the wood a short time, after I spray a sealer…I have been using minwax water based clear coat on coasters thinking it would make them washable…but it seems to draw up the soot and pretty much wrecks the design. I was wandering what I can do to stop this


Gotta do some cleanup on the material post-lasing. Damp cloth… old toothbrush… That should probably clean up enough of the soot to stop it.


Are you asking for something? Not sure what you’re getting at here.

Also do you have a pic of what you mean?
