When do you know that your weapon is clean?

After completing the M-Pro7 Gun Cleaning Process, patches may still come out a very light grey.  If there is no visible fouling, no further cleaning is necessary.  The light grey material is microscopic carbon deposits actually being pulled out of the pores of the metal and does not have a significant impact on accuracy.  In addition, it will be removed in subsequent cleanings until a point will be achieved where the patches will come out white.
