How to Restore Granite Countertop Color

Susan asked: How can I fix granite counter that has darkened? I just removed a fish tank, and the light granite counter is perfect. The problem is that the rest of the countertop has darkened. How can I lighten the countertop to match the original color that was under the fish tank? Thank you!

If you move a long-standing object from your granite countertop and discover a difference in color, it’s hard to determine whether the rest of the counter darkened or that spot was lightened. Because there are so many factors to consider, the easiest (and most likely) solution is to try to darken the smaller area to match the rest of the counter. Here’s a relatively simple solution you can test before you make it permanent.

You Will Need:


Steps to Fix the Discoloration:

  1. Apply a small amount of baby oil to a clean white rag.
  2. Rub it over the lighter spot (or a portion thereof). If your countertops are not properly sealed, the oil may stain.
  3. If the oil darkens the counter and you like the look, use Stone Color Enhancer to make it permanent.
  4. First, make sure the area is clean and free from debris or residue.
  5. Apply Stone Color Enhancer with a clean rag.
  6. Wait no more than 15 minutes.
  7. Wipe away excess Stone Color Enhancer.

Additional Tips and Advice

  • The baby oil will evaporate over time. This usually happens in a few hours or up to two days.
  • If you added too much Stone Color Enhancer, remove the excess with mineral spirits.
  • Apply Stone Color Enhancer BEFORE you apply sealer. If desired, wait at least 24 hours before sealing.

    I want to lighten my granite countertops to the original lighter color – not make the spot where the cookie jar was located darker. How can I do this?

    There is a light spot, as big as my fist, on my Brown speckled granite countertops; I don’t know what could have gotten on it; the maid cleaned yesterday and I just wondered if she could’ve mixed up the cleaner, as all I use is the cleaner for granite. Could food or alcohol do it?

    I want to lighten my granite counter back to its original color. We removed a microwave and found that the granite was exactly the same color as when it was installed. We want to get the whole counter lighter so everything matches.
    How do I proceed?

    I have the exact same issue as DJ. After less than one year, the entire countertop has darkened except for those areas covered by something (microwave, cutting board). I want to return the entire countertop to its orginal color so that it matches our backsplash. The darker color also has a yellowish hue that we don’t like.
