Does anyone know how to make their own hot tank? I clean alot of engine parts and I dont want to spend the money to professionally hot every little part I want clean. And I havent had good success with degreasers such as simple green or the foaming engine degreaser.

I have some super greasy knuckes/hubs and blocks with years of thick dried gunk on them. Whats the best way to clean this **** off?

 

nothing?
