Yes!

Miguel!

Were you ever able to get the outside of the nozzle Clean? Mine has a brown, burnt look and I would like to clean that off(or do all glue guns get that way after a period of Time?). Steve

Steve, I bought a glue solvent. I didn't know the ingredients of a glue stick of my glue gun but as it glues polyfoam, the seller adviced me to buy a solvent for polyurethane products and try if it works on them. A solvent made glue soft and easy to be removed off the noozle - I mean, from the outside. But it's quite hard for me to say if that would be working forever due to my glue gun is a new tool and hasn't had enough time to get the noozle really brown yet.

While solvents work fine on a glue gun, I simply take an old rag and clean off the nozzle when it is hot. This works fine as a rule to keep the nozzle clean. If there is heavy build up I grab my exacto knife and scrap the nozzle clean.

That's really good idea. I must try it on.

And what do you do if the nozzle is blocked up? Solvent doesn't work on compact glue inside the noozle and I'm not able to take it out of there with a wire or anything. I know it will be melting anyway once a gun is turned on and melting chamber is hot, but is there any anxiety about that may finally cause a bigger problem in the future if not taken out after couple of uses?

There really is not need to clean what is inside the nozzle. As you mentioned once the glue is on and in use it well push anything in there out.   Glue guns as a rule last for quite some time but I also treat them a bit like a disposable product since they don't really cost that much.  If one goes bad I just go out and buy a new one.   In the long run that is cheaper then buying products to keep the clean not to mention there are other aspects of the gun that well fail long before a dirty nozzle well cause a problem.

Yeah, you're right
