The caulking around my sink is brown and very sticky. I want to replace it. What type of caulk do I need?

What color do you want? There are lots of possible solutions from clear silicone to colored latex. Most any will work. Check with your local hardware store.

I wouldn't use any caulk for this application. Depending on your type of mount the sink probably has a layer of silicone between the sink and counter, no additional caulk is required. Scrape off the build-up and clean well.

Use a latex base, so you can make a nice bead and it cleans up with water.

If you want to do a very good job and ensure no water gets to the formica (I'm guessing that's what you have) and swells it, then pull the sink , clean the area, and lay down some Butyl tape. Remount the sink and remove the excess Butyl as it squeezes out.

Butyl is not a good choice for this application, especially in the kitchen. If you look up installation instructions for quality top mounted sinks silicone is the product of choice.

Use bathtub and sink caulking it is mildew resistant other types will turn colors as mildew infects it. Local hardware stores carry it.

And explain to me why that is?

Maybe it's because anybody can get silicone at Walmart, while Butyl tape requires a little more effort to find and most people have never heard of it even. As far as "quality top mounted sinks" show me a link for the cheap ones that say to use Butyl instead of silicone. [emoticon]

I've never seen butyl tape recommended for any sink installation.

As for the tape itself go ahead and use it, but before doing so I recommend you read the material safety data sheet (MSDS) on butyl tape including one of its ingredients called carbon black.
