Can someone prove to me why it's dirty...since you know so surely it is. Or is it because it's mexican gear...which you all shoot all the time without thinking twice about anyways. Let me guess...the guy who lives in the little house at the end of the street who is real respected says so and you wanna be cool to so....
To answer your question...the only thing that I know of is to rotate off of the trap shots for a while and to possibly get deep tissue massage to break it up. Find a different injection spot...there are plenty of them.
