bought a humidor online and the glue is seeping through the veneer is that going to be a problem ?

Do you mean there are stains on the cedar liner?

Sometimes wood sap from the cedar will seep out into the humidor.

I believe that you can take some alcohol on a cloth and wipe it away, then let the humidor sit open to air out and season it.

If this continues take s thin sheet of cedar and place it between the liner and your cigars.

Check with Bob Stabile from www.aristocrathumidors.com I believe he may be able to help you.

it could bu sap it is kind of sticky

contact the manufacture. you don't want glue (chemicals) mixing with your smokes.
