I bought my first rifle the other day.  I have a spikes tactical carbine.  I went and shot it to sight it in the other day and when I got home I cleaned it.  I sprayed gunslick foaming bore cleaner into the barrel and let it soak.  I did not think about the gas holes in the barrel and sat the upper upside down while it was soaking.  I cleaned the rest of the rifle and oiled it up.  I put the rifle up in my safe and when I got it out a few days later I noticed a bluish liquid on the end of the gas tube from where the foam got into it.  I have a feeling I am going to have to take the gas block and tube apart and do a very good cleaning on it.  What is the best way to do that?  I have a low profile gas block with what looks like two set screws in the bottom.  Do they sell long "pipe" cleaners that would work on the gas tube?  Being a "noob" sucks sometimes

Just flush it out with brake cleaner.

NON CHLORINATED so it won't eat any aluminuminum

Do I have to take it apart or do I just need to flush it from the end of it to the gas block?

No need to take it apart at all.  Just spray into the end in the upper.

Also, don't stick any pipe cleaner type shit into the gas tube or gas key on the carrier.  Self cleaning system, no need.

i wouldn't worry, i've always been instructed that the gas tube doesn't need cleaning because the high pressure hot gasses that run through it when it's fired blow everything out.  if you're really concerned perhaps the easiest solution would be to blow some compressed air down the tube (keyboard cleaner or air compressor).

Dont worry. Gunslick is all I've been using to clean my ar for the last 2 years.  Never a problem.

What I do.
Fill bore
clean lower and BCG and reoil.
Patch bore
run a oil soaked bronze brush down a few times.
Patch bore
Clean upper recver.
Run 2 oil damp patches down bore.

Does not always work. Just ask the guys that plugged the end with 22lr lead.

I'm sure it's fine, but if you're worried about it, just flush it with powder blast or brake cleaner, followed up with compressed air, and clean any shit out of the bore that may have come out of the tube.  As somebody else already said, don't stick anything such as pipe cleaners down the tube

I'm betting the blue you are seeing is just a reaction of the foam with a bit of copper fouling.  I'd just shoot it.
