Buying Guide: Key Purchase Considerations

- Stain types: Algae, mold, mildew, and organic growth may respond differently to each formula; choose accordingly.
- Safety and plant life: Many products state safeguards for lawns and plants; follow dilution and timing guidelines.
- Coverage and dilution: Concentrates extend value, but require proper mixing; ready-to-use sprays are simpler but may cost more per area.
