I regularly clean my epoxy floors (barn and garage) between projects and that usually involves:
1. Dirt, dust, other non-petroleum based project:
Sweep everything to the front, dustpan for 99%, then leaf blower out the front and off to the side.
2. Liquids non-petroleum based:
Absorb with paper towels or ready to trash rags, spray some diluted simple green, wipe it up.
3. Liquids petroleum based:
Absorb with paper towels or ready to trash rags, spray some brake clean, wipe it up.
4. Snow melt:
If still wet, squeegee out the front door, or to a drain/spot to let it dry out (if I don't want to open the door in the middle of heating. If dry, spray a little water and do the same.
5. Upkeep:
Spray down floor with water, use diluted simple green in mop bucket, mop it, then squeegee.
I like to keep it pretty clean between large projects but usually wait to do the upkeep step until I can get everything out of the area.
