Tenax is good stuff; the Italians don't make junk. This makes quartz look shinier, seem to have more depth, and makes water bead up better.

Based on a Technical Bulletin posted in February 2017:

Wilsonart® Quartz surfaces are non-porous, formulated to stand up to the harshest environments and do not
require sealing. They are highly resistant to chemicals, stains, heat, and moisture. To clean topical stains use
recommended products below:

 Windex®
 Greenworks®
 409®
 Mr. Clean Magic Eraser®

 Only use Spray Foam Bar Keepers Friend®

DO NOT USE: Bar Keepers Friend® in a liquid or powder or other forms of this product.

Use a clean damp cloth with any of the recommended products. Simply apply a generous amount of
recommended cleaners and gently rub affected area. Follow cleaning instructions for each manufacturer’s
product. Please use a separate cloth for each of recommended cleaners.

As a recommendation please clean
entire surface for a consistent finish.
Remember to avoid using cleaners that contain bleach or abrasive formulas. For a clean and polished surface
always ensure wiping up spills or standing water immediately.
