Original Gorilla Glue is an amazing product, but it comes with a massive downside: it expands as it cures. Last month, I was repairing a split oak chair leg. I applied what I thought was a reasonable amount, clamped it down, and walked away. The next morning, I found a rock-hard, yellowish foam bulging out of the joints.
Unlike regular wood glue (PVA) which you can sometimes soften with warm water, original Gorilla Glue is a moisture-activated polyurethane. Once it cures, it is 100% waterproof and incredibly resistant to basic solvents. You cannot simply wipe it away.
I started with a chisel, but quickly realized I was going to gouge the wood finish. Mechanical removal is too risky on delicate surfaces. You have to weaken the bond first.
After doing some digging, I found a solid workflow for this. If you are stuck in a similar situation, I suggest reading this breakdown on how to remove dried Gorilla Glue. It explains exactly when to use blunt force, when to use a heat gun to soften the adhesive, and how to apply acetone safely to break down the final residue without destroying your workpiece.
Next time, I'll remember to use masking tape around the joints before clamping.
