It’s difficult to avoid but that’s what a settling tank is for. Extract the honey into a bucket with a honey valve through your double sieve. Let it sit for a couple of days for the tiny bits of wax and air to rise to the top. Empty your honey into another honey bucket from which you can jar leaving the scum behind. If there isn’t much you can remove it with cling film. Lay a layer of cling film over the honey pressing it lightly down till all of it’s in contact. Pinch the middle and quickly remove. That will take most of it away
