Coolant leak turning white and crusty?

I have a coolant hose on my truck that leaks a bit and it runs down by the cylinder head area. Is it the heat that turns the coolant that into a white crusty color? Guess I need to take a tooth brush or something and brush it off. It has a stainless clamp that needs to be tightened periodically. It seemed pretty tight the last time I checked and I'm worried I'm going to crack the stand pipe that it's connected to if I tighten the clamp anymore. This goes into the cylinder head.
 
i just had some used coolant dribble down a hose on my Dodge in the process of flushing it and it left a white crusty stain along the whole thing. I think that's normal is all I'm saying.
 
That's probably the water glass formulated into the antifreeze. Many antifreezes have sodium silicate, which coats the cooling system insides to protect from corrosion.

The hose has to be cut off. Don't ask me how I know.

Nope I splurged and used distilled water the last time I changed the coolant.

Well, that rules out my theory of the white crusties being calcium deposits. . . .
 
Merk I think it's like the other guy said. Just the additives coming out from the heat.

That's what is left when G-05 leaks and evaporates. Simply the deposits from the additives. When the radiator leaked on my Explorer, that's what was left behind (along with a Y-pipe leak for the rear heater).

the long life coolants leave a white stain when they leak.

I see a cracked head(s) in your very-near future;

the white-crusty residue was your 'final warning' . . .
