One such case is at a joint line where two pieces of wood meet at an angle. In this case it is also o.k. Removing excess glue squeeze out. As mentioned previously, you should use a good amount of common sense during the construction process. Removing excess glue squeeze out is a perfect example of this.
Many woodworkers have a number of theories about how and when to remove glue squeeze out.
One theory I do not agree with is to remove the glue while it is still wet by using a damp cloth. By doing this, you are forcing the glue down into the pores. Furthermore, if you use a damp cloth, you are thinning the glue out thus it will penetrate even deeper into the pores of the wood. This method also makes it difficult to determine if all of the glue has been removed. If the glue has not been totally removed in some areas, it will act as a sealer and prevent a stain or finish from penetrating into the wood.
