I thought the problem was with just one drain, but it was actually related to the entire plumbing system. I had a similar situation: the water was standing in the kitchen, while the other drains were working fine. But as it turned out later, it wasn't a specific sink issue—it was simply the section of pipe running under the kitchen that was collecting the most sediment. This is especially noticeable on Mercer Island, where many homes have old pipes and tight connections that clog easily. When I realized home remedies weren't working, I started looking for local services and found detailed information about professional drain cleaning in that area https://bens.plumbing/areas/mercer-island/drain-cleaning/ . Specialists arrived with a camera and showed that there was a thick layer of old grease inside the pipe, and part of the passage was narrowed almost in half. After cleaning with hydrostatic pressure, everything worked like new: the water drained quickly, the smell disappeared, and the sound disappeared too. So if the problem is localized, it's best to immediately check the condition of the entire drain line—the blockage may be deeper than it appears, and the sooner it's detected, the lower the risk of an accident.
