30 SECONDS Foam Cannon Soap
Best for deep, multi-surface cleaning with foam cannons or hose-end sprayers.

The OXY-powered formula uses a peroxide-based system to lift dirt, grime, and organic buildup across exterior surfaces, including siding, decks, and roofs. One bottle cleans a large area by making up to 32 gallons of ready-to-use cleaner.

Buying Guide
- Surface compatibility: Determine whether your surfaces are vinyl, wood, concrete, stone, or roof. Some formulas are designed for soft washing, which reduces the risk of damage on delicate materials.
- Bleach compatibility: If you plan to use chlorine bleach, choose products explicitly labeled as compatible. Some blends offer stability with bleach while others avoid fumes.
- Concentrates vs ready-to-use: Concentrates require dilution but can cover large areas; ready-to-use formulas are convenient but may be more expensive per square foot.
- Foam performance: Foam aids dwell time and helps lift dirt; foam quality depends on the spray equipment (foam cannon vs hose-end sprayer).
- Fragrance and ventilation: Citrus scents can mask chemical odors. Ensure adequate ventilation when using strong cleaners, particularly indoors or in enclosed spaces.
- Application method: Consider whether you prefer a spray-on, rinse-off approach or a soft wash technique for roofs and delicate surfaces.
- Surface coverage: Look at dilution yields (gallons per bottle or per mix) to estimate total area that can be cleaned with one purchase.
FAQ
- What is the difference between a soft wash and a pressure wash cleaner? A soft wash cleaner uses low-pressure application to lift dirt and microbes, while a direct pressure wash may rely more on higher pressure. Soft wash formulas are gentler on siding, roofs, and aged surfaces.
- Can I mix these products with bleach? Some formulas are designed for bleach stability; always follow the label. Bleach can be corrosive and produce fumes, so use proper dilution and ventilation.
- Which product is best for vinyl siding? Products designed for vinyl siding include bleach-stable formulas and peroxide-based options that lift organic buildup without causing discoloration.
- Do I need a foam cannon? Foam cannons enhance cling and cleaning time on vertical surfaces. If you do not have one, choose products labeled as compatible with hose-end sprayers.
- Is a concentrated cleaner cheaper per square foot? Generally yes, concentrates yield more cleanings per bottle when diluted correctly, making them more cost-effective for large projects.
- What precautions should I take? Test on a small area first, wear gloves and eye protection, and avoid applying strong cleaners to plants or delicate finishes without proper dilution.
