Casey- Sorry you got flamed. Most people on here are nice. So what if your bike isnt the best quality. Work on it and learn, then the next one you buy will be MUCH better than the previous two. I understand your pain from the first bike.
Cleaning- Shucks almost anything. A soft brush and some mild detergent will get rid of the grease and grunge. DONT power wash it at the car wash! Because of its age you need to remove all the bearings, clean them, and reassemble. Old grease turns into hard lumps and stops doing its lubrication duties. You may run into the need for a few special tools.
There is lots of information on here when you need it. Learn to use the search function. SOmetimes you find exactly what you want and sometimes you dont. Then say you couldnt find it in a search and ask away.
Have fun with it.
