I purchased a used tt pro46. It runs great but looks pretty bad. Is there anything I can use to clean the entire engine. I heard you can dip the motor in a cleaner. Is this safe or can it be done at all.

Take a look at this thread. It also has other methods of cleaning a engine besides the crock pot. (I use the crock pot version of cleaning myself)
