I sweep mine out after each out after each outing (and during if it looks like it needs it) and about 2 - 4 times a year I will use something that kills germs.....Usually a spray pump then mop it up or use paper towels to wipe up everything (using my feet to move the paper towels around).
Mr Clean or lysol for floors works well (and smells great).
Next time I might use mop and bucket to get extra clean but it never looks bad (but no kids or pets - so your results may vary).
The earth tone vinyl floos hides dirt well.
