My nephew asked for a couple skulls for his kids. I don't have beetles so I figure boiling them would be the best option. Any suggestions?

Thanks in advance.

Norwestalta -

Over the years, I've probably cleaned well over 10,000 marten skulls for various research projects. For me, overnight in a crockpot is the way to go, then 3% hydrogen peroxide for about 4 hours. They're usually not greasy at all, and clean up nice. The enclosed photo was part of one years' collection (from interior Alaska). Good luck!

Gulo thank you. Do you put it on low heat?

With marten, I put it on medium or high heat. I usually do ten or so at a time.

On the other hand, you might try..............
Sheesh, you must have cleaned every skull that Ken, Barb, and Pete caught for several years, Gulo!
