Kitchen sink smells and needs frequent cleaning

So my sink will start to smell like rotten dead moldy zombie potatoes.
I take everything part (strainers, pipes etc) and clean it all up. It’s all plastic and for whatever reason I have to do this frequently.
my parents have the same materials in their sink and have never had any issues.
‘’what is causing this build up of “goop” in the pipes and cups thing strainer basket? Why don’t my parents have the same issue?

You're missing a drain trap.

Nope. The drain is trapped.
I have a similar issue, the grey colored gross stuff smell like rotten tomatoes mixed with baby poo
The bacteria that grow and cause this have a different environment at your parent's house.
What’s the solution?
Performing periodic cleaning and deodorizing tasks can support a fresh smell throughout your kitchen. The most common and effective method for maintaining a clean sink and drain is tipping a tablespoon of baking soda down your drain once a week. But for a deeper odor-fighting process, try the hot water, baking soda, and vinegar solution:
Boil a pot of hot water. Meanwhile, combine 1 cup of baking soda with 2 cups of vinegar. Pour the boiling water down your drain. Follow it with the baking soda and vinegar solution. Plug the drain to allow this home remedy to work. Once the bubbling has subsided, flush with hot water.
This the way we do it. Let drain “dry out” overnight. Before using sink, pour 1/4 cup of dry baking soda down the drain. Immediately pour a cup of a White vinegar down the drain. Let the volcano erupt (so don’t have your nose close when you add the vinegar).
Might try it again, same procedure since your sink stinks.
Now, after second eruption, you would pour boiling water down that drain.
If you were to have added baking powder to vinegar as mentioned above you’d have had an uncontrolled eruption. Combine them in the drain!
You don’t happen to have a disposer in another basin of that sink, do you?
No garbage disposal. Sink>plastic strainer cup>plastic slip joint>1-1/2 abs drain, trap, drain.
I periodically take it all apart and clean but I notice the pipe from the slip joint to the trap is gummed up with slimy bad smelling “goop”. I need to brush the pipes somehow or possibly just replace the whole assembly with new pipe.
I can’t figure out why we are having issues and no one else is
Maybe,
Because you dump more stuff down the drain, empty the strainer of the solids, and to conserve water you don’t pour quickly a pot of water to “flush” the trap. Just running water merely dilutes the trap, it takes a quick volume to really flush it.
Or
The trap is not working properly to keep the sewer “gas” from impregnating your sink area.
Or you’re my deceased mother-in-law reincarnated......
nice post like it
Are you saying that every time you clean it up it smells ok again, for a while? You mentioned that you have a trap, but that doesn’t mean it’s working properly. Do you have a vent pipe nearby? Without proper venting the trap won’t work correctly.?When you put water down the sink it will siphon the odor and gas protectant water right out of the trap. If you don’t have a vent one solution is a studer vent. They’re not legal in every state, but here in Vermont they are. They’re commonly used for sinks in islands where it’s difficult to put a vent stack. The studer vent is mounted under the sink so the top of it is above the water/drain level.
The smell is not sewer gas. The plumbing, and trap are functioning properly.
What’s happening is that there is, over time a “sludge” build up of god knows what on the pipes, and sink strainers.
Every few months I will take the sink strainers, drain pipes, etc apart and clean them.
I will also use a bottle brush as far down as I can to clean the inside of the drain lines.
Everything is fine, but after a while the buildup returns, and so does the smell.
Periodically between cleaning we will fill the sinks with hot water and vinegar and then give them a drain and flush.
Hmmm. I'm not a plumber, although I've plumbed 2 houses I've built, and have years of experiences fixing all the things that can go wrong in our 1840 house. Never had the issue you're describing. But one thing comes to mind is the water itself. When I built my house in the mid-80s I had a well drilled. Besides being the hardest water the driller had ever seen, it also had dissolved iron, which left a slimy reddish sludge. Do you have well water? If so, maybe something in the water? I assume you've eliminated one of the most obvious reasons, someone putting fat and oil down the drain, building up sludge and smelly bacteria. Spit-ballin' here. :-)
I just spliced a drain into our existing kitchen waste line, and the gunk build up in a 2" pipe is unholy. Imagine all the grease and oil from the sink and dishwasher accumulating in the pipes until they are half clogged with fat. I don't even know how the water moves through the sludge. Barf.
BTW, this may not be the best forum for plumbing problems. A good one I've gotten good answers from : https://terrylove.com/forums/index.php
My parents have the same plumbing (material types). They also,have the same water supply.
All of our cooking grease/fat goes,into an empty can, frozen, then thrown in the trash.
I will have a lookie at that other forum
Good luck. If you figure it out let us know!
I thought everyone did that?
Did what? Clean the plumbing, or put grease in a can?
Anything by that you'd have to chew up to swallow should go down the toilet. And try using a different soap. Alot of the "moisturizing" products contain oils and fats that can go rancid. Use just dish detergent (dawn) and water.
Interesting….. we do have a hand soap,for hand washing in the kitchen. Possibly a source of smell
Try using an enzyme/bacteria drain cleaner. I use Zep drain care once or twice a month and have had no problems with smells or kitchen blockage. I've owned my house for going on 10 years. I've had to snake the bathroom drains for hair, and the basement floor drain once but this worked very well in the kitchen and the house in general.
This should break up accumulated deposits and their odors in your drains. I'm using Zep because it seems the most cost effective, there are several other enzyme/bacteria drain cleaners available.
