What's the best way to take care of granite countertops?

Granite counter tops and back splash newly installed but they don't shine like I expected. Do they need to be polished and, if so, what should I use?

As normally produced, granite countertops do not "shine" - more of a slightly milky sheen like a regular glass light bulb. For a high gloss, it needs to be either diamond polished HEAVILY to a "glass finish" (pricey), or more commonlyu - sealed with a high-gloss sealer - and any new countertop should be sealed with 2 or maybe 3 coats when new, BEFORE use so it does not trap dirt under it, because the surface is really quite porous and has numerous dimples and low spots between the mineral grains. That is pretty much true of any countertop material - though wood and formica and laminates use different types of sealers like waxes or urethanes or varnishes rather than silicone or silane sealers.

Talk to your installer about what you expected versus what you got, and how many coats of sealer was applied to the countertop - and quickly, before it picks up much dirt or soap scum, through it will need chemical cleaning before reapplication regardless because even a bit of soap or grease can cuase the sealer to bubble and blister and not protect properly.
