I have used both VetRx and Mineral Oil by themselves with good success in getting rid of mites, but the key to using either one is to pour it into the ears liberally to ensure that the mites inside the ear get soaked with it. A day or two after applying the above to the ears, use some cotton swabs to get any scabbing or collected wax out of the ears, then put in a second dose of mineral oil.
It's not a bad idea to keep a spray bottle of Bactine around, either. Often times, the affected rabbit will scratch their ears and open some cuts in the ear lobe in the process, and Bactine is good for healing those cuts up.
As for fur mites, I use Equate (Wal Mart) topical ointment, and it heals up very well in a relatively short time. It's the cheaper form of Neosporin ointment, and it works the same.
Getting rid of mites is a serious matter because absent of doing so, it's a problem which will keep reinventing itself.
