Can someone please tell me the details of the acetone cleaning method?

Ambiguous question. Do you want to clean your acetone, or clean DMT by using acetone?
I will try to ask clarifying questions next time. I want to use acetone to clean dmt crystals.
Can you give us the method you’re referring to ? It’s impossible to fill in the details without having the right information.

This method separates DMT from many other impurities:
The FASA Method - DMT-Nexus Wiki
Acetone alone will dissolve freebase exceedingly freely, but DMT fumarate is practically insoluble in dry (anhydrous) acetone.
If you want freebase again, a further process must be used with the resulting fumarate, such as sodium carbonate paste followed by drying and pulling with acetone. Evaporation of the acetone yields goo/wax, so you'd need to use naphtha or heptane to recrysallise, either in the freezer with slow cooling, or via slow evaporation, if you want nice big crystals.
I have seen this mentioned a few times, how dry exactly does the acetone need to be? anhydrous acetone can get pretty complex to prepare depending on the definition of anhydrous.
Since the tek doesnt specify the process of drying acetone which is required for anhydrous chemistry with acetone, can i take it that you are ok to simply use something labeled 100% acetone? or do the trace amounts of water interfere?

You could try using the search function or just use google.
Acetone is hygroscopic and also self-condenses in the absence of water, so truly anhydrous acetone is virtually impossible without some ridiculously stringent practices. Fortunately, that would be overkill for the FASA method, and there other ways of proceeding that don't even require acetone as well (but of course, they don't get called "FASA").
There have been figures discussed in some of the original FASA threads where the water percentage immediately after any particular drying method was quoted from the literature.
