Quartz is not explicitly named, and the product's ingredients and pH are unavailable. As a hard, non-porous countertop material, ordinary use is reasonably compatible.
Why
The manufacturer approves countertops and counters and provides directions for hard-surface cleaning, supporting normal compatibility with quartz.
What to do
Use as directed, wipe after the stated contact time, and rinse with water if used on a food-contact surface. Test a small inconspicuous area first, especially for coated or specialty finishes.
pH
No pH value available in official evidence.
Relevant chemistry
Official evidence supports cleaning, sanitizing, and disinfecting claims; specific ingredients and pH were not provided.
