Does this make sound for both an inhale and an exhale?

Yes, it makes sound both inhaling and exhaling. You can also make a cool sound by reversing the air suddenly mid-blow.

I would like to have this laser engraved. What type of metal is the housing made of?

I just tried a magnet on it, and it's non magnetic. I doubt if it's stainless steel, but it very well could be. In my experience whistles are generally made of brass and then nickel plated.

What to use to clean innards?

I've never had to clean the inside. It does appear to get stuck after not being used for a while, then I just give it an extra hard blow and it seems to be ok again.

At times, this does not work... and then at other times, it works perfectly. What's going on?

Hi there: The spinner that makes the sound, is on an adjustable axis. I opened my whistle up and placed a very light small drop of watch oil on the spindle. I backed the axel spindle adjustment screw out, turn to the left, just a tad. Put it back into the silver part and give it a try. Remember, just a small amount of oil or adjustments. My whistle did the same thing.

Le encanto a los niños

Un capricho un poco caro, pero hizo feliz a los niños. Se escucha como una verdadera sirena de ambulancia sin resultar tan molesto como otros silbatos.
