• Bleach test: Apply diluted Clorox to small spot, wait, rinse. May lighten iron oxide stains.
• CLR (Calcium Lime Rust remover): Test on small area. Designed for mineral stains. May work on iron deposits.

Sweep granules off hardscape before watering. Use drop spreader with shield near edges. Ironite stains are cosmetic—they don't damage concrete.

If stains persist, they'll weather eventually. No perfect solution exists for iron oxide on porous concrete.
