Catch telltale glue spots before they tattle
Too often, you don't see spots of glue film on your project until after you've started to apply the stain or finish.
Expose glue smears by wiping all joints and adjacent areas with mineral spirits or lacquer thinner. The glue smears will remain light-colored but the surrounding wood will darken. Be careful not to soak the wood with solvent.
