Many years ago in the U.S., we could buy small bottles of "Strip-X" made 
by GC Electronics.
It is no longer available on the market, but I recently found such a 
bottle, and the stuff   _does_   remove enamel like a charm.
The contents are:
- Methylene Chloride (75-09-2)
- Phenol  (108-95-2)
- Ammonia (7664-41-7)
Proportions are not listed.

The mixture exhibits the consistency of chocolate syrup.
