What is the best DIY way to unstop a kitchen sink w/out using draino

Do you have a drain snake? Plunger?

Try sprinkling some baking soda down the drain and then pour in some vinegar. Sometimes the chemical reaction that takes place can unclog a drain.

You could try using baking soda in the drain and then pour vinegar down the drain. Cover drain because it will foam up. After the baking soda and vinegar have done their thing then pour a pot of boiling water down the drain.

First try a plunger. Pour some baking soda down the drain. Then pour some vinegar down. Immediately cover the drain with a damp cloth. The force of the reaction should push the clog through. If you have a double bowl sink cover both drains with a damp cloth.

Try pouring white vinegar down and follow with baking soda.Wait awhile and run very hot water.

Depends on whether you know why the drain is clogged. If you have a double sink, is the clog on the side with the garbage disposal or on the other side? Need more information to be able to help...

You could use a Jam Jar. Full up the bowl halfway, and turn the Jar Upside down and Plunge it over the Sink hole and try to build up a suction by keep pumping up and down quickly. Then when you think you have done it enough, pull away the Jar. The Suction should have released the jam.. Otherwise use the " Sink AND pLUG uNBLOCKER"............

baking soda followed by white vinegar...let it foam for 45min. to an hour, then flush drain with hot water...

A few ways that I have used are the zip pulls designed to clear drains. They are about 18 inches long and they pull hair and everything. They are very inexpensive (usually $2-6). Since this is a kitchen sink, this may not work, particularly if you have a garbage disposal.

There are two other options:

Option 1: from under the sink, place a bucket or flat pan under the drain trap. Unscrew the trap and remove it from the sink side of the pipe as well as the drain side. The water in the trap will run out. That's normal. You can then take it outside and rinse it with a hose under pressure. (make sure no one uses the sink in the meantime). If the trap is off for more than a short time, push a washcloth into the end of the drain to keep sewer gas from backing up into your house. Obviously leave a bit out so that you can pull it out.

Option 2: take a shop vac and set it up for water use (remove paper filter and replace with foam filter) push the hose down into the drain and try to get it to seal. If it doesn't, it still may work. If it doesn't, wrap a wet washcloth around the hose where it comes into contact with the drain to seal the gap. Usually, this will pull the clog up into the vacuum.

cup of vinegar & about 1/2 cup of baking powder. It works wonders. I do mine usually about once a month to month in a half. (white vinegar)

I have used a bathroom plunger on my kitchen sink....just plug up the air holes if it is a double sink and plunge away. After it is unplugged, pour cloryx down the drain once a month....a little over a pint.

Lowe's sells a device for about 4 bucks that is about 18 inches long with hooks on each side, if the clog is not too deep, it will pull it up. Good for maintenance too so you don't get a clog.

Vinagar, baking soda and hot water!

Thanks everyone for your ideas
