Ubatuba Granite appears Dull – What Do I Do?

Jackie F. sent an email question:

I have granite in my kitchen and was told that I didn’t need to seal it.  It is “Uba Tuba”.  It has been in for about 1 year.  There are no stains on it but it seems to be looking dull.  I was told to put lemon oil on it and then buff it.  That just seems to smear.  Can you help me with this?


I replied with the following suggestions:

Thank you for contacting us. This is a common question we receive. Here are some thoughts:

  • Granite is polished and often ‘resin impregnated‘ in the factory.
  • The polishing process involves grinding with progressively finer abrasive grits until it is highly reflective.
  • Granite will never wear away under normal use on countertops.
  • Any apparent ‘dullness’ is most often caused by cleaning products, food spills, and inferior polishes used in an attempt to restore the factory shine.
  • Ubatuba is very resistant to stains, but it does have small pits that can look ‘dull’ in reflective light.

Solution: See Deep Cleaning page HERE If your browser does not support links please copy and past the following URL:


  • Deep Clean using HMK R55 Intensive Cleaner, and Rinse Completely.
  • Seal Granite to prevent future stains using HMK S34 Impregnator
  • Maintain the granite using a pH neutral cleaner like HMK P24 Stone Soap. This will help prevent product buildup that can affect the shine and polish.

Finally, some clients like having that New Polished look and use the HMK P21 Polishing Paste, applied after granite is sealed. This is much like waxing a car, giving it a new shine and smooth feel. This is a topical approach and is much like polishing furniture that needs to be done regularly to achieve that waxy look.

I hope this helps you with your granite. Please call if you have further questions.
