I would never clean dishes in the black tank.

Best approach.

I will give you two answers as to why someone would wish to "Clean the black tank"

One: (which I fund humorous) is that some folk like to clean... Don't ask me why.

THe second and the one I find reasonable. Sometimes if you clean it.. The sensors will actually show EMPTY when you are done.. Believe it or not.. Had that happen a time or two when I cleaned.. but then I've only cleaned (in 13 years) very few times.

I finally said "@Q#$@# The sensors".

So I'm curious, when do you put the tide in and what is it "work well for us" doing?

DW uses tide HE for our laundry, so already have it in the house.

We camp a great deal, 3 month/year or so. Our trailer is a 2010. After about the first year of camping I added tide to the grey/black tanks just before we came home to our mostly full tanks. (I have a dump station at home). When I dumped the grey water had more "junk" particles than normal. and it took less time using the black tank flusher to get the black tank reasonably clean. Since then it seems the laundry detergent keeps stuff in suspension better than no detergent.

And at that time I had the cheap factory tank sensors, which after a few times out with the tide, were working about as well as one can expect with the cheap sensors.

Since added the sealevel gauge so can't say how well the laundry detergent would do long term on the sensors.

The laundry detergent is cheap enough that we continue to use it. We have very soft water most places we go so how it would work alone in hard water, don't know. Calgon or similar would also help if the water is hard.

Why do I need to clean my black tank (or gray tank for that matter). I don't intend to eat or drink out of it and next time I use it I'm just going to **** in it again.

I always wonder the same thing.

Clean....Not Sanitize
Aka keep the crud from building up

we use liquid laundry detergent. It's now formulated to work in cold water, even though hot is better. Not so with dishwasher soap, it's formulated to work in hot water.

laundry detergent usually is formulated to be more aggresive and harsh than hand soap, normal dish soap etc. that besides cleaning must be formulated to be ok on your hands etc.

I just fill the tank halfway with fresh water and drive over some bumpy roads for a bit and it cleans it right out (knocks the TP shards off the sensors). Add a couple of bags of ice if your really feel frisky.

I don't think the tabs would dissolve well in a gray or black tank. They are intended to dissolve in the 100% hot water that dishwashers use. And as STBretired said, they are pretty alkaline, much more so than liquid detergents.

If you want to keep stuff from sticking to the sides/bottom/sensors (at least to some degree) use some Calgon or Borax dissolved in about a quart of hot water, plus a squirt of liquid dish detergent. Put it in the tank before you move the RV and it will slosh around and get distributed pretty well.
