What do most of you clean excess and old grease from the various pivot points with? I just purchased a 2012 Cat 262C2 and had a full service done on it with the sale. I have completed a couple of grease service intervals since. Living in Arizona, the dirt/dust is heavy, causing the area around the grease points to be covered with a thick excess. My goal is to take an old toothbrush and remove that buildup and ideally would like to use some sort of solvent. What would be compatible (just in case some of it got into the Zerk fitting or pin seals)? Peace, Dr. Z.
