Try the Extreem to clean it and the regular to maintain. I have used this product for a few years and find it does the job and for a reasonable cost.

You might also take a look at your holding tank vents.

I dumped a big bottle of pine sol in mine with about 5 gallons of water and took it for a long drive.

I found that regular backflushing with the Valterra Flush-King, and following the "GEO" method, keeps both the grey and black tanks clean.

I put a full pound of baking soda in my tanks with a gallon of water whenever my coach is stored for a month or more. I buy the bags of Arm & Hammer at Costo and never have a problem. Its cheap and no chemicals.

You have vent valves on your drains. Look under your sinks. They may need to be replaced. Easy on and off. Get replacements at Lowes.

Liquid Dishwasher (mechanical/electrical appliance) liquid and install a Camco Tornado tank flusher.

Here is a link to my grey tank flusher install. Re-design Black Tank Flushing System

My grey tank no longer has any chicken parts in it.

Good Luck!

Two tasks.

Clean and prevent.

Best way to clean is dump a little bit of powder type drain cleaner (lye) into each drain with just a tiny amount of water to activate it to clean out the traps.

At the most used drain dump in maybe a cup at a time with maybe a gallon of water to get it into the tank.

Glasses and gloves preferred...

Let stand overnight then flush all drains and repeat one more time just because.

Last is fill gray tank to near top if you can see it or know sensors are correct and let stand for a day or three.

Drain and flush.

The lye will not harm any part of the system but will attack anything organic inside so it will be spotless unless you have a lot of solids so repeating may be needed.

After cleaning or while waiting verify all vents working as mentioned above as well as review of procedures with "staff" to verify what has been allowed into the system.

Home sink with disposal allows organics into the system while not so good on an rv.

Full timers can give great advice there so heed and seek their advice for that.

Wife uses 1/3 cup of Oxyclean mixed with hotwater. Works best in almost empty tank, just before you start travelling for the day. Sloshes around for a few hundred miles. When you dump at new park, amazing the chunks of ??? that run out.
Also, as previous posts, check the plastic vent valves under your sinks. They have a rubber flap that tends to stick open after a while. Very cheap to replace from Home Depot / Lowes. Just screw out and in.
