Marine head toilet bowl cleaning...

[northshoreone]

My Intrepid was totaled in the Ian so I happened to be looking online.....never a good thing as it always cost money...and found an immaculate fresh water Formula 33 that I will close on Tuesday of next week. It has a few issues, most from very low usage..one being the the head was not emptied last fall and the toilet is disqusting!! Shocking knowing the past owner, although the kids are the only user's the past six years.
My question is how do it clean the bowl without destroying the inner working of the toilet? The toilet is a Jabsco electric flush unit. I will spare you all from the pic of the mess!
Thanks in advance

I’ve had very good results with Sew Clean. Let it fester for a while but plan to pumpout within a day of when it hits the tank. Then flush and fill the holding tank with fresh water to dilute the remaining chemicals. It’s so good at liquefying all things in the “sewer” so if it will stink bad if you let it hang around. It also kills all natural biological so drop a few tablets of microbes in there after flushing with fresh water. https://www.trac-online.com/products/descalers/sew-clean

On regular porcelain stuff you can use a pumice stone.

Sew clean works great . I wonder how often it should be used to clean hoses of calcification.
