Since treating my Bunny with Xeno for Mites he smells bad. Is this normal?

[Alfie Bunny Bear]

My Lop is just over twelve months old. I recently found a dandruff patch on his back between his shoulders, so I took him to the vets. They said he had mites (under the skin parasite variety and gave me the spot on XENO plus an anti bacterial wipes for the infected area). Since treatment, my bunny smells less like a healthy, clean sawdust smell, to something that resembles a rotting dustbin!!! Before I pay a fortune for another vet consultation, can anyone help explain why or what I can do. I don't want to bathe, as I've read bunnies suffer from dry skin already and bathing can make it worse. Many Thanks.

Please dont bath your rabbit.

What are these antibacterial wipes you were given?

That seems slightly counterintuitive to give a spot on, which is designed to stay on the skin, and wipes which would just remove the spot on? Also, why antibacterial wipes for a mite infection?! Very strange.
