Sweetened Black Vinegar

I’m new to this condiment, having used this vinegar only for Pigs Feet With Black Vinegar and Ginger. It is dark and slightly sweet.

Since I usually use regular, distilled vinegar to clean burnt bits off my stainless steel pots I tried cleaning with this vinegar. After all I had half a bottle left over from cooking pig trotters. Not sure what else I’d used it for. The soapy suds turned black but my pot looked beautifully polished!
