how to get mud out of carpet?

my friend and i did something verry stupid, and we ended up trashing someones [pontoon] boat. its not that bad. i feel extremely guilty, and scared to get caught, even though the druggies of the neighborhood would be more likely to be blamed than me
theres mud and fire extinguisher powder caked into the carpet, does anyone know how to get that cleaned, without any special detergents or steam cleaning?

i have to sneak back to where it is in the middle of the night, and its all snowy outside, so i dont have many options. my friend wont be there to help me, ill be all alone [great after watching horror movies]
any suggestions? please help!
