How do you manage gunge when warming stored honey?

I extracted the summer crop in mid August and passed it through a fairly course sieve into 30lb honey buckets. I now wish to prepare soft-set honey by mixing one bucket of summer honey with half a bucket of spring honey (partly OSR), after warming to 35C. After mixing and stirring I will pass through a finer sieve into the bottling tank.

On opening the buckets from the store room I found that the now-set spring honey is topped very little scum/gunge, however the summer honey has a thick 3-4mm layer of hard white 'lard'. I thought it might be easier to scrape it off before warming rather than warming then skimming the gunge off using cling film.
The amount of gunge is more than I remember from previous years. Grateful for your thoughts and advice. If I don't do anything the jarred honey is likely to be covered by a layer of gunge.

warm it overnight, your 'gunge' will turn into a creamy foam, skim it off with a large spoon, stir honey them mix both

Yes, warm it overnight, skim off the crust - nearly all should come out if you're careful - pour through a double strainer and mix from that bucket.

Thanks. I'll report back
