how do you clean onyx For regular cleaning, use a cloth or sponge with your favorite non-abrasive household cleaner. Most cleaners will work very well with your Onyx product. The two most important aspects of cleaning are the hardness of the water and the frequency of cleaning. We recommend applying a protective / polishing product like Gel-Gloss™ after each cleaning.
