Simple Green foaming coil cleaner gallon (128 fl oz) — NSF C1/K5, non-caustic, clinging foam

Simple Green Foaming Coil Cleaner (Gallon) is a professional-strength, non-caustic foam that penetrates and lifts grease and grime from HVAC coils while remaining NSF C1 and K5 registered for food-processing use.

This concentrated foaming cleaner is formulated to cling to vertical and hard-to-reach coil surfaces, loosening oily buildup and particulate matter that reduce heat exchange and system efficiency. The ready-to-use gallon (128 fl oz) container supplies technicians and maintenance teams with a durable, stable solution that rinses away with condensate or light spray, and it contains no added dyes or fragrance for neutral facility use.

How does this cleaner remove buildup without harsh chemicals?

The formula relies on a thick, pressurized foam that adheres to coil fins and penetrates greasy residues, breaking them into removable particles without using caustic alkalis. Because it is non-flammable and non-caustic, it reduces the need for aggressive neutralizers while protecting coil surfaces and surrounding materials.

• Thick clinging foam for extended contact time on vertical surfaces
• Non-caustic composition to minimize corrosion and material damage
• Non-flammable for safer storage and use around electrical equipment
• No added color or scent for food-safe and neutral-environment applications

Can I use it on equipment in food-processing areas?

Yes — this Simple Green formulation is NSF-registered under categories C1 and K5, making it suitable for many food-processing and commercial environments where incidental contact is a consideration. Follow facility protocols for application and rinsing when required.

• NSF C1 and K5 registration for appropriate food-area use
• No added dyes or fragrances to limit contamination risks
• Apply with standard spray or foaming equipment per facility guidelines
• Self-rinsing action on condensate-producing coils reduces manual rinsing

How should technicians apply and rinse the product for best results?

Apply the foaming cleaner using a pressure sprayer or foaming gun to achieve uniform coverage over coil faces and hard-to-reach sections. Allow the foam time to penetrate and suspend soil, then let condensate or a light rinse carry residues away; stubborn deposits may require a second application or mechanical agitation.

• Use a pressure or foaming applicator for even distribution
• Let foam dwell to break down grease before rinsing
• Self-rinses on condensate-producing coils; otherwise use low-pressure rinse
• Repeat treatment for heavy or baked-on contaminants as needed

What size and packaging details should I expect for storage and handling?

This product comes in a one-gallon (128 fl oz) jug designed for workshop, service-van, or storeroom use. The container is sized for portability and repeated on-site applications while remaining within common industrial storage guidelines.

• One-gallon (128 fl oz) container — contractor-friendly volume
• Item package approximate dimensions: 8" L x 8" W x 12" H
• Package weight around 5.0 lbs for easy lifting and transport
• Made in the United States with professional-strength formulation

Who this product is for: HVAC contractors, facilities maintenance teams, food-processing plant operators, and building service technicians who need a reliable, non-caustic coil cleaner that clings to vertical surfaces and rinses clean. Choose Simple Green Foaming Coil Cleaner when you require a neutral, NSF-registered solution that balances strong grease-cutting performance with safety and compatibility for sensitive environments.
