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:
- Wipe spills immediately—even tap water. Use mild soap + water, always rinse + wipe dry.
