Clorox Tilex combines a mold and mildew remover with the power of bleach to kill 99.9% of mold and mildew on a range of surfaces. It is designed for indoor and outdoor use and tackles stains on nonporous surfaces as well as areas prone to recurring mildew.

CLR’s mold and mildew remover emphasizes a bleach-free formula designed for safety around families and pets.

Buying Guide: Choosing The Right Mold And Mildew Remover
Consider the following factors to select the most suitable product for your space:
- Surface compatibility: Porous vs. nonporous surfaces require different formulas. Bleach-based products often work well on nonporous surfaces but can damage natural stone or wood finishes.
- Stain intensity: Deep, pigmented stains may need a stronger, fast-acting formula designed for heavy discoloration (such as RMR-86 variants).
- Odor and ventilation: Many removers emit strong fumes. Ensure proper ventilation and PPE, especially in enclosed spaces like bathrooms or basements.
- Safety for occupants and pets: Bleach-heavy products can irritate skin and eyes; consider bleach-free options like CLR for households with sensitivities.
- Application scope: If you face recurring mold, a kit with multiple formulas or a combination bundle may be cost-effective and more convenient.
- Contact time and rinse requirements: Some products require dwell time before wiping or rinsing; follow label directions for best results.
- Environmental and surface safety: Look for multi-surface compatibility and pet-friendly formulas when possible.
For ongoing prevention, combine a trusted cleanser with moisture control, improved ventilation, and routine cleaning to reduce mold growth risk. Always read the product label for surface compatibility and safety instructions before use.
