I have similar strategy. I don't do the toilet BOMB. It probably helps some but I never have a buildup so I don't.
"10. Close the black water tank and run the flush water in for four(4) minutes. Do not let anyone distract you at this point."
I set the timer on my phone for 10 minutes with a LOUD "BARK" when it goes off. This way I don't get distracted!
I do the 10 min flush twice. First time I close the Grey and flush it also.
I can't take credit for this setup but it's AWESOME as I don't have to do anything but turn the valves to flush the tanks.
