Question Black tank

[Beginning rv rookies]

Hello beginning a new adventure in life, my wife works from home so we ordered satalite internet, I drive semi locally so home every nite, we just bought a 2014 crossroads that has sat for a couple years with sewer in tanks, VERY ripe, I have tried the orange balls and several deodorizers and dumped several times but cant get rid of that horrific smell, we will be living in it full time in 2 weeks, can I put bleach in there or anything else any suggestions are so appreciated thank you

Not sure but someone will eventually chime in, but until then, welcome aboard!

You may have dumped it but have you done several rinses? Some on here use Dawn. Not sure on the bleach but tanks need to get rid of the dried and stuck waste before deodorizing.

If there was waste in it for sometime, you might try a septic tank bacteria packet and fill with chlorine free water. Let it sit for a week or 2 then flush several times.
Now I have not tried this, but have used the packets in my septic tank to breakdown solid material.

Just an idea...

Run water in all locations, p-traps dry can allow stink to come into the coach. Rinse tanks several times and give it time, it's not going to turn off like a light bulb but I think with normal use and keeping all p-traps filled with water it should go away.

Thanks for all the tips I flushed 4 or 5 times with an agitator and drove it around, much better
