My kitchen sink was always a bit slow. Could sometimes help it by dissolving accumulated grease with a kettlefull of hot water poured straight down the drain, but it was still marginal improvement.
I know, off topic to original post, but reinforces the fact that it's time to remove and inspect!
I had one similar, our kitchen was at one end of house and sink was the only thing on the line to the 'stack'. It took multiple minutes for a sink full to drain. I drain-o'd it, snaked it, boiled it, replaced the under-sink pieces, etc. all to no avail. I finally crawled into the crawl space, tapped on the line and it went THUD, not ping like a typical galvanized (which is what it was back then) would do.
I sawzall'd the pipe at each end to get it out, it fell on the ground so hard it would have hurt if my leg were under it, not at all what I expected. (yea, in hind sight I should have supported it, but I was young and fearless back then) It was all I could do to drag that sucka out of the crawl space, when I got it out and sectioned it in the middle, that 4" was constricted the entire length down to barely an inch of opening and the crust was HARD as a rock.
Replaced it w/ new 4" plastic, problem solved, and family much happier!
