Odor how do I get rid of a foul odor in the dryer

If you have a bad odor,pull off the vent line from the back and see if an animal is dead there,i've found dead birds,mice and a possum,in the blower wheel of some dryers,they get in from the outside hood,once they get into the vent line and slide down they can't climb back out or if the dryer is running the wheel does a job on them.also if you had some painting or staining done this also can make the dryer smell bad.this is going by what i've found when someone complains about an odor in the dryer.hope this helps,one more thing if the motor is overheating from the dryer not being cleaned out it could have like a shellac smell,you might have to take the dryer apart to see what's stinking or it could be something near the dryer,when the air is heated in the dryer it makes the smell worse but if you find waht is causing it and remove it the smell will go away,if it is from a dead animal you can wash down the area with soapy water,you don't want to use anything with a strong smell because your clothes will smell of that when the dryer heats up.what does it smell like?
