Other than a brush what are some of the tools needed ( Got all the wrenches just the cleaning tools). Did you just scrub it or did you use some b-12 cleaner ( I think that is what it is called) Also to help eliminate the build up couls you spray some teflon in that area to help eliminate the build up from sticking again? Just wondering, i am not sure how it would affect the engine if any got in to the cylinders.
