Please help with smell

I know this topic has been asked about 1,000,000 times, but I haven't read about this particular situation, yet. Somewhere in my living/kitchen area, or beneath it, is a sour chemical smell. The closest thing I can think of, is pickle juice. There was carpet deodorizer behind the couch, when I looked but I sniffed every inch of the carpet in the slide and couldn't smell this. I'm stumped. At first listen, most are inclined to say black water, but the bathroom and bedroom smell fine. I'm hoping someone has can shed some light on where this might be coming from. I'm at my wits end. Nothing will kill this odor. Thanks for any info.

I don't know that I'd call the smell of a dead rodent anything near like pickle juice...but is it possible that an animal or rodent found a spot to hide in and then died?

Other than that...I'd suspect a galley gray tank it stronger under or near the plumbing for the sink?

I've taken to putting a treatment in our gray tanks, mainly because one of my DW's friends is terrible about letting scraps of fruit and vegetables go down the drain and they can stink things up pretty good!

Good luck in locating the source.

Someone mentioned in another thread that the batteries can off gas an acid smell. Just a thought-but easy to check!

First a couple of questions, is this a new trailer, a new to you used trailer or have you owned this for awhile? If this is a new trailer, is it the formaldehyde smell they come with? If it is used, did they have pets or could they have spilled something on the carpet? Next, have you made sure there is water or antifreeze in your p traps? There is a product called zeolite that gets rid of smells, but you need to find the cause first.

One thing that now one has mentioned is if you get RV Anti Freeze in your hot water tank and warm it up, it can cause a real bad smell that is hard to get rid of.

make sure the sink traps have water in them and you will have no odors from the tanks.

You will get a sour smell from your grey tank if it is not cleaned out regularly. If you have a sink near the smell area that could be it. The tank will get a build up of oils that hold odors. Get a grey tank deodorizer it comes in a large tablet and dissolves in your sink right into the tank. It will break down any oils in your tank and give it a lemon smell. Do this about every 3rd trip at least.

Last year we had an un-findable smell and it turned out our black tank had shifted and fllen off the "minimal" cradle that held it in place. consequently the discharge pipe had slipped out of the tank and the odor was from the tank. You couldn't really see anything because of the underbelly panels blocked the view of the tanks.
Good luck

Thanks everyone for the replies. I got sidetracked with a lot this week, but I think I found the source. It is the grey tank smell, but not from the sinks. Apparently the smell is coming from below. The guy that was helping me, said there wasn't anything wet, underneath, but that he couldn't see the tank, itself. He said maybe a coupler is loose or something. Anyway, the smell was coming through a hole in the floor that wasn't sealed. I filled that hole with spray foam and can't smell the smell coming up, anymore. However, the smell is still in the living area. Should I close the valve to the grey tank and poor the solution in? I'm staying at a campground longterm, so I just left the grey tank valve, open.

You have a leak somewhere. Spraying foam in some hole will make it come up in another spot. I'd be concerned of a buildup of flammable gas of some sort. Don't ignore it.
