Hi,
Did you find the mineral oil caused flaky shedding? - that's been reported as one of the problems using it but I have never tried it and was curious.
But, to be brutally frank, if you have mites then you want to follow Deborahs advice and get some provent-a-mite.
As with everything follow the directions exactly.
The can will also last a long time and it never hurts to have one handy.
