Does anyone know an easy way to clean a glass pipe so it looks pretty much unused without boiling it and shit? Also i know plenty of people that bring weed through airports but i still get sketch about it, is it pretty much cool? Where would be the best place to put my weed and pipe? small amount of weed and small pipe

What kind of pipe are we talking about? Steamroller? Spoon? Corn Cob?
If it's glass you can just soak it in high-proof or rubbing alcohol overnight. Just rinse it well afterwards and let it dry before you use it again.

If you're just taking the weed and pipe with you with no intention of smoking on the plane, just put the pipe in the middle of your checked baggage. They won't find it.
The weed will be a bit harder because of the smell. Put it in a baggie, wrap that with plastic wrap real tight, and tape that shit to your leg/sack.

70% Alcohol and salt works great, the best way is to pour some in your bowl and shake the solution around in it for a minute or so. Otherwise you could just use the alcohol on a Q-Tip or something.

if its a short trip, like only a few day thing, just avoid the hassle and make a bong when you get there.....or buy some rolling paper and make a joint.

as for hiding the weed, search button/google, its been answered so many times

Just put it in your boogie board bag.

clean it, put it in checked luggage
