Vinegar & Baking soda for Black Tank Clean out ?

A full timer told me that the best way to clean out solids build-up in the Black Tank is to use Baking Soda and Vinegar. Does anybody have any experience doing this? It sounds to me like it would generate a whole lot of activity, and might just damage something.

Vinegar is an acid. Baking soda is a base. They cancel each other out. It is a waste of time and money.

Human solid waste is very greasy and needs soap to get it in suspension so it can be flushed out.

The GEO method works very nicely. Use this before traveling so it can slosh around in the black tank.

Flush out the black tank thoroughly. Put in 6 gallons of water. Flush down the toilet: one cup of water softner and one cup of laundry detergent. Leave it in for as long as you can or till you need to dump again. This only works to clean while you are traveling. Do it for a few times while traveling and the tank will be all cleaned out. You will notice it will be very easy to get cleaned out on the first dump. Then do it every now and then as you feel it is needed

Though the other poster is quite right that acid and base do cancel each other.

The two mentioned do it violently and very exothermic Generating a lot of heat and action.

I do not, however, know if it would work,, I prefer calgon, dawn dishwashing liquid (Blue not yellow) water and drive to slosh it around.
Home is where I park it!

for a foaming cleanse
fill potty with vinegar and water
then fill with water and 1/4 cup baking soda
then flush
it will create a foam and will help remove the goo
then a good dose of calgon water softener and flush away.....

we use the geo method nite before a trip in the gray tank to help cleanse it and then a good tornado wash as we dump

I'm a full timer, and my tank has not been flushed out or cleaned in six years or so, I just let nature take care of it, which it will, odorless too!

Well, it will if you use nothing but lots of water, no additives.

Weekenders, of course, benefit from the cleaning out bit.
