If you want to go industrial strength, skip the marvel, and use CLR, household vinegar, Oxalic Acid, or molasses. Give it a good soak then try to turn it over. Beware though, these will clean it down to the bare metal, which means it'll flash rust in no time flat unless you get some oil or something on it to protect it.

Yes, I think it was the rodent urine. The head looks fine, just the top of the piston, and inside of one of the cylinders.
Just to be absolutely clear: I am to use only one of these, or a combination? How long should I soak it? Should I flush it out with oil afterwards? Will I damage the (good) metal if I leave it too long? Which one is best?
