- Eco and safety profile: Look for zero VOCs, peroxide-based or citrus-based formulas, and minimal harsh chemicals to reduce environmental impact and indoor/outdoor exposure.
- Stain and mildew effectiveness: Consider whether the product targets black mold, green algae, tannins, or gray weathering, and the level of scrubbing required.
- Coverage and concentration: Concentrated formulas often require dilution but can cover larger areas. Check projected square footage for budgeting.
- Application method: Determine if the cleaner is designed for spray, brush, or pressure-washer compatibility, and whether an included scrub brush is provided.
- Sealer prep compatibility: Some cleaners are specifically formulated to prep surfaces before sealing; ensure compatibility with your chosen sealer product.
