There has been a lot of weird tips for cleaning and regreasing a Linear Ball Bearing on the web, and I hope to briefly clean (hah) that up here.
Before I go any further though, I'm not sure how much difference this will even make. On a Voron 1.8 (which this tip is exclusive to), there are four smooth shafts an aluminium plate is moved up and down with. It moves very slowly.
This video shows that cleaning the grease off (isopropyl), then regreasing it with White Lithium grease makes a big difference - they are quieter in operation, and have less resistance (you can see this @9:21 ) .
I done this by using an applicator, and packing the grease inside by using two rods together to help push the grease on to the balls.
In this video, the parts used are an 8MM smooth shaft and a LM8LUU (tip applies to a LM8UU as well).
If you are an Aussie, this is the grease:
