How to Remove Dark Areas on New Venetian Gold Granite

Shirley from Virginia called to ask:

“How to I remove the dark spots on my granite around my sink and where I prepare food?”

Upon further discussion, I learned that her granite was installed only one year ago, and she had sealed it with a sealer her installer recommended that she purchased at Lowe’s.

In addition, around where her soap dispenser is located, and where she rolls out dough on her countertops is the areas that appear dark.

Diagnosis:

These signs indicate that the sealer she purchased is not providing adequate protection. Where soap and water drips from the dispenser, it absorbs into the granite and darkens the appearance of the stone.

Also, where dough and cookies are prepared on the counter, it is also darker in these areas, while the rather unused areas remain much lighter.

Granite needs to be Deep Cleaned, and Sealed with a Professional Grade Impregnator.

Step 1. Using HMK R55 Intensive Cleaner, pour full strength onto darker areas, and use a soft-medium bristle scrub brush to agitate the cleaner. Allow product to dwell (sit on the surface) for 10-15 minutes (must remain wet) and scrub again.

Step 2. Use a sponge to soak up R55, and blot dry with a paper towel. Immediately move to Step 3.

Step 3. Rinse VERY well with clean warm water until no soap suds remain. Then rinse one more time. Allow to dry overnight.

Step 4. Repeat if necessary to remove deeply imbedded stains. If  area is clean to your satisfaction, move on to step 5.

Step 5. If stains are completely gone, then protect stone with a quality impregnating sealer like HMK S34 Silicone Impregnator.

    Thank you for sharing this info! We are having the same problem with our Venetian Gold (cinnamon sand) purchased through Home Depot. Frequently used areas have darkened significantly and we’re starting the warranty process. Having this information will help when they come out for our warranty evaluation. Initially they’re saying they are losing their polish which doesn’t explain the darkening. These were sold pre-sealed and carry a 15 year warranty. They were already staining after 1 year and look terrible now that it’s been 5 years.

      Home Depot uses slabs supplied by a company called Cosentino.
      They claim this 15 year warranty, so hold them to it!
      The dark areas are entirely from penetration of water, foods, oils, etc from use. The stone is not protected adequately.
