To clean a snake is quite simple. Its much easier than cleaning any other animal out there. But you have to be careful. A snake can kill you hours after its dead! It still has muscle reflexes just like most lizards etc... If you ever seen a chicken still run a bit after its head been cut off you know what i mean. So approach a dead snake slowly and from behind. Sometimes, what you may have thought was a dead snake isn't. The vibration that you make may just be enough to get it to strike. But lets assume the snake is dead. You never want to pick it up if you can help it unless you have a special tool. You can do a couple of things. 1. is just bend down and cut off its head with a big knife in one chop. 2. step on its neck slowly with your shoe applying just enough pressure to keep it in one place than cut off its head. You never want to step on a snake body hard its like stepping on coil its springs out. Make sure you wear thick boots when dealing with snakes. To fielld dress them hang them by their necks from a low branch make one long shallow cut down the middle and you can essentially peel their skin off at this point, or you can use your knife to remove their skin just like any other animal. you can also nail either the tail or the neck to a a flat piece of wood and skin them in the same manner as hanging them froma branch. Once you have skinned the snake. Cut deeper down the middle of the snake to ensure you don't cut into its guts. cut all the way down and remove the guts. Rub it with salt and coffee ground and vinger if you have it on hand to reduce the strong taste. Remove the any all fat you seee thats where some of strongest smells comes from.
Oh by the way do rinse off the coffee, salt, vinger after about 10 minutes.
