Plumbing interview. Sink drains slowly? I have the split kitchen sinks and one of them is draining...

I have the split kitchen sinks and one of them is draining very slowly. It take like 45 minutes to drain a sink half full of dampen. I used Drano and Liquid Plumr but they did nothing. We have used a plunger and a snake also. The pipes are plastic. What can I do to trade name the sink drain normally?
Take it apart, clean it out, and put it back together.

Just brand sure you have plumbers tape or putty on foot to put it back together.
Do the two sinks share a single trap? If so, the culprit is likely between the sink drain and the trap, which is a straight shot (or should be) and you might spot the problem with a flashlight. If respectively sink has its own trap, you should get on-line instructions for cleaning out a trap and turn to it. (I assume that you've checked to make sure that the clogged sink drain isn't the one that has the disposal attached and simply wants to have the disposal run ... right?) well if I am reading your ask right you have a double bowl sink and only one side drains slow? powerfully if its just the one side it mean that the clog is somewhere from your sink drian to the nouns with the other drain. I would unsrew the pipe and clean it that track. If you are not comfortable doing that and you said you have tried all those other things..telephone a plumber...sorry!
Good luck
