Hello
First i must sorry for my ugly english
I have some idea about cleaning MHRB before STB extraction, with butane like hash oil extraction.
With this method i can pull out some non DMT oils and other crap?
Or maybe that low temperature destroy DMT?
what with other gasses, DMT is soluble or not?
I mean in, argon, acetylene, pure oxygen or others.

DMT is soluble in butane, the cold wont do anything to it. One problem with liquid gasses is that once you get it to disolve it starts to precipitate back out straight away because of the low temps... so work fast!
I'm unsure if you'd pull any spice out before it has been basified though.

Personally I wouldn't bother as its not really neccessary.

I read in this board that DMT isn't soluble in butane

I use butane to disolve DMT for changa preperation. It is soluble man.

Ok i believe
After the evaporate butane, what form of DMT will stay?
What is the efficiency and durability DMT after?

I'm not sure if what you're suggesting would work.

When making honey oil you're collecting the trichomes that have broken off due to the cold temps and pressure of the butane. It wont remove any plant fats or crap from MHRB.

Your best bet is to do a basic extracton and a recrystalisation... or an A/B tek.
