Black water overflow

[hpdean]

Ok. I made a big mistake and didn't open the black drain before turning on the flush. As a consequence, my tank overflowed. My question is what is the best way to clean up the mess?

Depends on where it overflowed.

Up/out of toilet......probably should pull toilet/clean under-around it with bleach mixture

If it overflowed into underbelly.......tank doesn't have an overflow so that means it came out via one of the line connections on top of tank (vent line and/or toilet line) OR tank split.
Need to remove underbelly covering, insulation and inspect tank/tank line connections for damage and then clean up with bleach mixture, new insulation
