RV Tank Maintenance

Any ideas as to the best way or cleaner to keep my Sensors clean and not show incorrect readings. I sometimes empty the black or grey tanks and still get readings of anywhere from 1/3 full to 2/3-full.

I have a macerator so ice cubes will not work plus I longterm camp and do not want to break camp to drive around juggling the tank contents..

I'm looking for a really good cleaner and dissolver that will do the job..

    I use one of those wands with the spinning head. Open my toilet and rinse up and down. Rinses out the black tank and cleans the sensors. Available at Walmart or rv place

    I've had very good luck with Dish Washer soap. It's made to break down grease...which helps clean the gunk off the sensors. However, I've always put it in with about 1/4-1/2 tank of water when traveling, no sure if it would work if you don't slosh it around. Good Luck !

    No one successfully 100% is able to keep the sensors clean. Even external tank type appear to be unreliable.

    Happy Camper seems to do a good job, use plenty of water. I’ve cubes do zip, nada, zilch.

    We can tell when ours is getting full, so don't worry about the tank sensors/gauges anyway. We have tried various things suggested on here and some worked for a couple weeks. I think most methods suggested are for weekenders who drive, dump and flush their tanks every few weekends.
