Ok, this is a dumb question, but I never really used greaseguns before, and I just changed a cartridge today. Taking the top off, there was a big glob of grease left on the tube. Do you all scoop the excess grease off, or just change the cartridge, and mash it all together with the grease glob still in place? I scooped the excess grease out with my finger, and put it in a peanut tin to use for latches and stuff, but it's a lot of grease, and I'm gonna end up with way more grease than I reasonably use. So... You guys that use greaseguns, what's your grease change procedure?
