I have a problem with a glue dispenser bottle (it is the Gorilla adhesive bottle type)
the glue has become hard in the tip of the bottle and so no glue comes out, i have to unscrew cap and pour onto the wood.
I'm not familiar with the Gorilla Glue brand in particular, but in terms of general glue-bottle-unclogging tips:
- Try pushing it out from the (removed) top, starting from the smaller end, with a pin (blunted if you can) or a bit of small rod. If the glue hasn't bonded with the plastic of the top, it could well be easy to just push it out. If there's any overspill over the outside of the top clean this off with a fingernail or a knife first.
- If you have trouble, try warming the top up in hot water before you start. A lot of glues and a lot of plastics become softer when you heat them, making it easier to detach the glue chunk.
- If the top is made from flexible plastic, try flexing it, or squishing it in pliers a bit - the plastic and the glue will not be exactly as flexible as each other, so this again may help separate the two materials from each other.
- Don't push or squeeze or bend or heat anything too much - having a clogged-up top that you can't squeeze glue through but which protects the glue in the bottle is still better than having a broken top which allows the entire bottle to set/dry/cure/whatever! Squishing the plastic can also make it stretch, which can be good for clearing out a clogged-up bit of glue, but bad if you do it anywhere near a thread, which will then no longer engage properly.
