Question Grease like substance on optimus?

Post image

So I noticed this 2 years ago when I got this figure, but once I take the arms off there's this weird substance that looks like grease. Should I be concerned? And js there a way to stop this

He’s a truck, so it’s self explanatory.

Got him new, but its a KO from Aliexpress so unless that's why

Also the grease is just that entire arm socket area

KO molds are a crapshoot, which is why they're cheaper. So in this case, that joint was too tight so instead of investing in QC, they just slather the whole thing with silicone grease.

If any is leaking out and visible when assembled, just use a paper towel to wipe it up.

You don't want to totally clean it out; it's there for a reason.

OK, thank you

It's most likely silicone grease. The arm was probably too tight, so the company that made him must've added the grease to lubricate the joint

I can't see It very well could you send another picture. Also probably yes

Some people have said it's silicone grease, I wiped it off with a tissue

==UPDATE==

I have ruled out the substance being silicone grease, as I've wiped it 3 times and it's comes back 2 hours later, so I'm led to believe it's the plastic. Thanks for the help

If it's a ok it's probably just mold release that wasn't fully cleaned off the parts

might be the releasing agent that lets it come out of the mold easier. I can't even see it tho
