How to clean campground grill grates before use

[Gambit McCrae]

Im "affraid" of crapping my brains out like I did last weekend and the past 2 days. I just want to ensure a clean surface to cook on.

Sounds like you got a different problem.
Aluminum foil (a bit of aluminum foil, or a rock in a pinch) will clean it physically.
Fire will clean it fine, biologically.

Not cooking your meat to temp, maintaining good hygiene (personal and kitchen) or treating your water will solve your other problems.

A thought as well-
When I bring fresh meat- I freeze it all prior to leaving and wrap it in foil. Hamburger or pork products- use first day. Steak, second day. Ham Steak or other salt heavy item- maybe three days.
I don't take a chance with chicken or fish.
Dry ice is another good trick in this regard, and makes a nice chilled libation.

You do realize that your own kitchen sanitiation more likely to make you sick than a campsite grill, right?
