What’s the best method to cleaning off the stuff G uses to pack their new uppers for transit?  

I remember folks talking about what the protective lube was but I can’t remember.  

Is a decent wipe down good enough or are we talking a thorough stripping?

I've always just wiped with a paper towel or rag.

It’s personal preference, but since Geissele is so high end I like to get it pretty clean, and then lubricate it with a high quality SYNTHETIC lubricant on the inside. I use a synthetic wax on the outside because when I was training in the heat (very hot where I live) after one day of training the castle nut and end plate (not Geissele) was totally covered in orange  rust from my sweat, just from one day.

So once I got off the surface rust, I then used synthetic wax on all of the steel/iron parts to block it from any humidity/salt in my sweat. It worked like a charm. It still looks brand new since that first application. Just an idea that’s worked for me and my buddies too.

As for removing the packing grease stuff, I personally use 91%-93% rubbing alcohol with a microfiber towel (you can find them cheap in Walmart with the rubbing alcohol too). And totally removes everything bare, so it’s bone dry & clean ready to accept the high quality lubricant you use (I use Slip2000 EWL grease and oil too).

You can do what you want, but waxing the steel/iron parts of everything has been a game changer for me and haven’t had a single spec of rust in two years. I use something called “Renaissance Wax” however I’m sure a regular synthetic automotive wax would probably work just as well. Hope this helps.

I’ve never used it for this purpose (protecting, not cleaning…) but not surprised as “Renaissance Wax” is a must have product for me.  I’ve been using it for decades for so many things, it’s incredibly versatile!  I’d be very curious to hear of anyone else has ever used it for this purpose…..

Doesn’t G use g96 on uppers/rifles? @gacs

I know several others who’ve used it for protection (not just on steel, but on aluminum too) and it’s repels everything, even in the most humid, unforgiving elements in tropical swampy weather. One moderate application has lasted over two years now and is working just as good as cerakote imo.

I doubt many people have thought of using wax, let alone a synthetic microcrystalline wax like Renaissance Wax for this specific application. I thought about it, used it, saw how flawlessly it worked even under the worst conditions, and then told my friends/colleagues about it, and they’ve had the same results. But I use it purely for protection, I absolutely don’t use it as a lubricant at all. I can’t recommend it highly enough.

I thought they mentioned before it was G96 synthetic, and if not its something that smells very similar.
