I recieved this gas can and i asked the guy what he used it for and he said he used it for fuel for his chainsaw.. i looked inside it and has a black sludge at the bottom. how do i clean it out for safe use to avoid engine damage?

Seriously? You can probably buy a new 1 gallon can for like $12. Go buy one if you need it that bad.

The sludge is probably 2 cycle oil and varnished gasoline. Splash a little fresh gas in it and let it soak several days, shake it around from time to time.

Toss some gravel in it and shake the snot out of it (strap it to a paint can shaker?), maybe you can agitate it clean. (This actually is one way to clean up a rusted gas tank too.)

throw a lit match in it.

Put the can in the bottom of your hot tub for a few days.
But seriously there is stuff that is supposed to neutralize oil I think. It was used in that big oil spill, it's called 'Corexit'. There are probably consumer level products like that, that you can buy.
