The infamous Heng Long Glue Monkey strikes again.

Any suggestions how to remove this glue without dissolving the plastic parts as well?

Instead of Chemicals I would use a VERY sharp craft knife blade to get under an edge and gently I SAID GENTLY lift it away.

I have no experience of the Heng Long Glue Monkey
I would try warming the parts in warm/hot water the glue MAY become pliant and you can peel it off. Or freezing the parts the glue MAY become very brittle and you can chip it off.
Or try both together the rapid contraction/expansion of the plastic MAY cause the glue to lose its grip.

agree with jarndice a sharp stanley blade or small chisel

I have long experience with a sharp hobby blade, even scalpels (yikes!), and jarndice and Tiger 76 are right. However, if I am right about HengLong goo-glue, it is not a "cement"; that is, it actually does not "weld" the plastic, but just hardens and actually remains pliable. I would first try Dogberry's tricks. Then, too, here are actually hard plastic razor blades available from online sellers. You could try one of those as it might be tough enough to scrape off the goo-glue, but not damage the HengLong plastic.

Good Morning,
After many years of battling the after effects of over zealous Hot Glue\Rubber Cement\Whatever it is that HengLong is currently using\ application, Chemicals should be your last resort unless you are dealing with Super Glue. In this case as these other Fine Gentlemen(tm) have noted, Heat coupled with a sharp Blade ( preferably plastic since such are now available ) to gently lift and scrape away the excess until the parts can be separated. Good Luck and Go Slow.

Painless

Chisel blades are very useful, just wear glasses as they're a bit too easy to snap and tend to go a long way...... Image to show - left hand blade https://cpc.farnell.com/productimages/s ... 996-40.jpg Very useful for those hard to get at places.

Try both methods, but I find HL likes hot glue for holding the wiring (easy to pop off), and a MEK solvent for joining plastics. And even that seems to have variants like a very thin clear type, and then the gloppy stuff like you show (possibly just contaminated with plastics on the brush?)
Regardless, it's a solvent and eats and welds the plastic, so I'm with the chisel and knifeblade club.

Gluemonkey might be coming up on retirement!

Mike.

Maybe a Dremel tool with a grinding attachment (and a light touch).

I use the chisel blades also, but I also got like 7 stitches from one where I jabbed it into the web of my hand. Now that hurt. I have a sacrificial blade holder that I use a small brass hammer on with my chisel blades. The end of the holder is mushroomed a little from the hammer, but I find the hammer actually gives me more control.
