take them out of the cage,put a dab of perfume on their heads(being careful of eyes) and a dab on the rump.Then put them back into the freshly cleaned out cage.I have used this successsfully with fighters the idea being that nobody has their own smell or can distinguish strange mice by their odour.Harmless and worth a try.

They do groom themselves straight away.No problems encountered though,I suppose it has to be pretty safe as we humans squirt it on ourselves.Anything smelly would do though,even a blast with mite spray.
