Water blaster in a drum & skim the grease off the water.

I would suggest this method, but use the steam cleaner.

You will want some kind of surfactant to break up the grease first maybe? Then rinse with hot water?
Or use something like methylene chloride? It’s a powerful degreaser (but extreme care must be observed when using it). In which case go to someone who uses methylene chloride like an engineering company or alternatively call a chemical company and ask them which of their customers might be able to help.
Perhaps boiling the items in a vat of water might melt the grease and cause it to float to the surface so it can be skimmed off?

better than dealing with nasty chemicals, but depending on the item, rust could be an issue if you can’t dry out the items properly?

DCM is dammed expensive, low boiling point. Trichloroethylene is what's used in the engine cleaners but it's a closed system where it's boiled & there's a condenser setup that condenses it's fumes so they rain back down into the item being cleaned ( which being colder, it also condenses on it ) washing the grease off it.
I'm with using a steam cleaner if it's available. Water blaster in drum if it's not. Maybe followed by a engine cleaner cycle at the auto car wash + rinse.

Another more ‘friendly’ option is to use D-limonene.
They look good. Assuming there's no PCB in it, we can scrape the grease out and steam blast them in a barrel.

Give it back to whoever created the mess and let them deal with it.

Petrol is a good degreaser and cheap and dangerous, but you really need to identify the grease. Perhaps the manufacturer of the components may know what grease was used.

I've a similar parts washer. The pumps are not solvent friendly so have to use water based cleaner product. Ok for cleaning engine parts etc but would be hopeless for removing bulk grease.
Go for the totally environmental friendly solution. Find a pile of old tyres chuck your bits on top and drop a match.

We already have a small parts washer. It has a pump, and appears to have kerosene as a solvent. Nobody seems to be concerned about that. I am concerned!

heat will make grease liquid potentially drain it. mostly first

How about putting the objects in a bin full of hot water. The grease should float on top of the water. Scoop it off, then put the next object in the hot water. Have an electric immersion heater in the water.
