Stop throwing away the small sponge from the scourer you may use to wash pans etc. Use the softer sponge section and cut to a size slightly larger than the space on both parts.
The foam pieces hold the IPA well and also slows down the IPA's evaporation.
As you've seen in the photo, this does a great job of lifting out grunge & debris from the screw's thread.
Once four pieces of foam are cut to size wet the whole of two sponge parts with IPA to clean the lead screws.
Once cleaned, give it a couple of minutes for the traces of IPA on the screws to evaporate then replace the dirty sponges with clean ones to distribute synthetic grease across the length of the lead screw leaving just a fine film. I put four small 'dabs' of grease spaced across the length of each screw, the sponges do the rest.
The magnets keep both sides together and by powering the lead screw up and down two or three times, the cleaning tool will quite naturally follow the screw's thread. The handle (intentionally angled) gives an element of stability to the process. Especially so for the BambuLab X1 printer's rear lead screw which is behind a metal panel and only accessible through a narrow vertical slot.
Great idea Jal!
