One way to open a slow kitchen drain is by using a plunger on the drain. If the drain is still slow put some baking soda and vinegar in the drain to loosen any debris that remain in the drain.
Kitchen sink drains are a fertile environment for certain forms of life, and these can cause the drain to run slow. When hot water is run down the drain, it kills some of the lifeforms, allowing the drain to run freely for a while. Try using a drain cleaner, or a drain snake, to clean out the drain. Never pour grease down a drain, as it cools and solidifies quickly in the pipes.
Call a plumber to snake out your kitchen drain line. Do NOT pour acid down your drain. Do it right and it will be almost good as new. (I'm an optimist)
A double kitchen sink that is draining slowly could be clogged with debris such as food particles. A snake is a tool that can be found at a hardware store that is used to remove things clogging flow in a drain.

Bathroom or kitchen should be square and level. The plumbing drain lines need slope to drain properly.
