I’ll clean any fittings with dirt on them before starting, usually use a blue paper shop towel. If recessed pin fittings have dirt packed in them I’ll find a twig or stick sized right to dig it out. Then I just pump grease in each fitting until some starts to push out the joint. Do EVERY loader and backhoe pivot every 8-10hrs. Some things like axle pivots or control pivots may only need it every 50-100hrs or more, check the manual or service chart. I don’t bother with cleanup unless the grease buildup gets excessive, my machines may look like a mess but by god they are well greased lol.
