In my view, Cloaca Cola (with apologies to Raymond) is drinkable
provided that it is at least 60 degrees Fahrenheit colder than
the ambient temperature. And still liquid.

When you finally discover that 2 thirds full bottle of gone-flat Cola that
you bought last Christmas for young visitors, you can pour it down the pan
and leave a few hours. It's quite an efficient toilet cleaner. Possibly not
very environmentally friendly though.
