Unplug

Ice cubes with plenty of water and then drive it around to loosen the crud then drain. I also have a turbo wand that I use too. It is attached to a hose and inserted thru the toilet flap to flush the tank

Add some water softener, dish soap and hot water and drive around for a short while and try it.

Repeat as necessary.

edit: I see you got it under control. Now always keep the black tank valve closed until the tank is near full and use plenty of water on each flush.

Put two 20 lbs bags if ice down the toilet with the water and then take it for a ride. The ice should help "scrape" the bottom and sides of the tank.

I'm guessing you didn't watch the video?

I just bought the sewer solution for dumping. The flushing function "jets" water back into the tank. I'm sure after one or two pipe bends any "jetting action" is diminish to near nothing, but just an idea?

Why not use water and some RidX? Let it dissolve the solids and then fill and dump.

I keep 2 gallons of water and a container of the poop destroyer chemical in it at ALL times...at full hook ups, I leave tank closed until its full, then I empty it, then I put another container of poop destroyer chemical and 2 gallons of water...the tank is NEVER empty...

my wife has been warned repeatedly to monitor the black tank so she doesn't find out its full the hard way...I rarely use the camper toity as most campgrounds have excellent facilities

all solids (paper and waste) have to be dissolved somewhat...I know some people will tell you they've never used chemicals, just water...but everyone I know who owns a trailer uses some sort of chemical...for odor and to dissolve solids

I use dishwasher detergent dissolved in warm water, it's designed to dissolve stuck-on solids. Do your gray tank as well, you'll be horrified at what comes out the first time you do it! I don't do this all the time, just periodically to give it a good cleaning.
