Sewage smell, also how do you clean your tanks?

Sometimes the bad odor can spew from the tank roof vents and blow down into the coach thru a vent or window.

We've been doing the old white vinegar thing in the tanks with a couple gallons of water after dumping for the drive home for about 19 years.
Citrus cleaner helps also.

Also something like Tst keeps odors down from the black waste tank especially during hot weather.

Hope you get things taken care of.
