Meet the Expert: Tom Munro (40 Years in Stone)

My name is Tom Munro, and I’ve been in the tile and stone business since 1984. I founded Supreme Surface, Inc. in 1996, and for the past 15 years, I’ve specialized in surface care.

As a stone specialist, I talk daily with homeowners, fabricators, and industry pros. I constantly hear stories that bust the myths pushed by quartz marketers—especially about stains on white quartz countertops.

Biggest Quartz Myth: “Non-Porous = Stain-Proof”

Quartz countertops are marketed as durable, non-porous, and low-maintenance. The truth? They’re mostly right—but not indestructible.

  • “Non-porous = stain-proof?” Wrong. Spills can etch or stain if ignored.
  • White quartz shows every blemish, spot, or etch mark—frustrating thousands of homeowners.

I’ve seen it all: stained countertops ruined by coffee, wine, or even tap water left to evaporate.

Why White Quartz Stains: The Hidden Resin Flaw

Yes, quartz is durable—but not invincible. Here’s what damages it:

  • Stains and etching from acidic spills (wine, lemon, vinegar, harsh cleaners).
  • Discoloration from excessive heat, UV rays, or chemicals.
  • Chips from impacts.
  • Cracks from thermal shock or movement.

The #1 culprit? Unsaturated polymer resin in manufacturing.

  • Pro: Makes quartz non-porous.
  • Con: Weakest link—melts under heat, etches with acids, wears from abrasives like Magic Erasers.

Protect Your Quartz: 2 Dead-Simple Steps

Prevention beats cure. Follow these for spotless white quartz forever:

  1. Wipe spills immediately—even tap water. Use mild soap + water, always rinse + wipe dry.
    Realistic? Most skip this.
  2. Upgrade your game: Spray on Supreme Surface® Granite, Quartz & Marble Treatment with ioSeal®—the all-in-one cleaner, polish, and protector against water spots, stains, and etching.

Bottom line: Quartz rocks—when protected right. Stop the myths. Start protecting today with ioSeal®.
