Favorite detergent powder for bear skull degreasing?

Looking for opinions on everyone's favorite detergent powder for bear skull degreasing? I normally use "awesome liquid degreaser" on whitetails. But these bears are stubborn. Thanks everyone.

Dawn dish soap is the gold standard

Borax and dawn, then leave out in the sun submerged in 10% peroxide for a couple days then dry.

Local guy here with beetle operation soaks them for 2 weeks in water/dawn solution. borax also helps

Commercially I used dawn dish soap and industrial strength ammonia. The other trick is to keep the water warm at about 105-110 degrees and change it when it gets murky. I also would soak them cold in acetone for months sometimes. Bears are really stubborn when it comes to getting all the grease out.
