My sink has a moldy, mildew smell that I cannot figure out. It smells like a dishrag that has soured. I do not have a disposal or anything, it is just a plain sink. I have looked under my sink and there is a small dried puddle but it does not stink under there at all and it does not seem to be leaking anymore for whatever reason.
I have used bleach and I did the baking soda and vinegar thing. It works for a day or two and then that smell is back. I can walk by and get a whiff of that smell and it makes me furious! What can I do? Is there a service for this?

You are probably getting small whifs of sewer gas which means your sink drain is most likely in the pre-stages of getting clogged.
Since the sink is still draining, you can't use a plunger. You can try drain cleaner, but those never work for me. You can go to a store such as Home Depot and buy the smallest snake they have. A snake is a flexible metal strip used to remove clogs from drain pipes. Stick the snake through the sink drain, then push it far enough to get past the trap. The trap is the U-shaped area of the drain pipe under your sink. You will hopefully push some of the clog past the trap, and break up the rest enough that it can be flushed down the drain.
Clean the sludge out of the sink, then run both faucets full blast for a minute or so. If the smell is gone from that point on, you're all set. If the smell remains or returns, the trap will have to be removed, cleaned and replaced. It is not a complicated job, but if you can't do it yourself, a friend or relative might agree to do it for you. Otherwise you'll have to call in a plumber.
Do you live in the country? It may be your sewer backing up, if so call a plumber or have your septic tank pumped out. The smell can be very harmful, so get it checked out.
Some kitchen sink drains have a vent device that is located right under the sink. It's a lousy design & I've only seen it installed in rural areas where building codes are not enforced very effectively. It is also sometimes installed on sinks located in an "island" counter. All house waste drains need to be vented to prevent the "glub-glub" sound that also can cause back-ups due to too much air in the waste pipes.
If you have this undersink vent, it can get wet on occassion & mildew forms in it. Have someone who knows a little about plumbing to see if this is the case. They are easy to spot. A plumber can remedy the situation.
You can purchase the stuff for bacteria in the pipes. Certain times of the year I find this issue. Maybe we don't use one bathroom more than the kitchen, etc. Running daily water is important.

I have a bathroom sink drain that stinks. I have put vinegar in it and used the steam cleaner using the steam down the drain. Last night I used Liquid Plumber.
