dirty tanks - need recommendation on what cleaner to let soak in tanks.

Having extreme difficulty in getting sensors to register correctly. Any advice would be appreciated. Thanks

Dump the tanks and refill approx 1/3 and add Dawn ( about 6 oz. ) . Now take a ride and dump when you get to your next destination.

Never had a problem with any of our previous rigs. Used chemicals and waited till the tanks were 3/4 full.
Now the previous owner of the Magna must not have known how to treat the tanks as the black always read 1/4 full when nothing would come out. Over the last few weeks I've kept water in it and fresh chemicals plus used the built in tank flusher. For the first time I got the black tank to read 0% full. I think there's still some "stuff" in there because I added a couple gallons of water and chemicals and now it reads 1/4 full. Making progress!!

I agree with using the Happy Camper. I've been using it for years and no problems. The extreme is supposed to do wonders.

Another way to clean your tanks, Dump a bag of ice cubes down your toilet and take a drive, you will be surprised the amount of crud that comes out of your tank.

I've used a cup of bleach and a cup of Calgonite dishwasher liquid per 20 gal of water. then 2/3rds fill tank with water. Let it soak for a couple of days, take it for a good drive, let it soak for a couple of days. take it to the dump station and dump. Flush well with fresh water. We always put 2-5 gals of water back into the tanks with a good shot of Calgon (1 oz.), after we dump. The electronic sensors seem to get screwed up by just the smallest amount of waste; toilet paper. onion skin, whatever.

From time to time we'll do the dishes in a large bowl instead of the sink. When done I'll squirt more dish washing liquid into it, and dump it in the black tank with a good flush. It stays until I dump.

RV Digest it is awesome:


Once clean, we have our own home brew that works for us:
Equal parts
Pine Sol
Dawn (ONLY Dawn - best grease cutter out there!)
Calgon (Liquid)

We make a gallon & add 4 oz RV Digest it and dispense via the blue streak:

Oh, we use the same home brew in our Galley & Gray tanks as well. Never had a problem.

Dawn dish soap and some Calgon water softener--dissolved in water before pouring down into either drained tank. Add about five (5) gallons if water and then drive to your destination. When leaving, do a dump, rinse well, and repeat tank doseing. Do this a few times and things will start to smell "rosy" (yeah, sure).
We did this on our 1989 and now sensors work well.
