Frequently Asked Questions
Will this foam cleaner work on an outdoor condenser unit covered in pollen and grass clippings?
Yes. The foaming degreaser is specifically designed for outdoor condenser coil cleaning, lifting pollen, grass clippings, grease, and general grime from the coil fins before a water rinse.
Can I use this product on a patio air conditioner or a portable AC unit on the deck?
Yes. The spray-ready 20 oz size and the gallon refill are both suitable for cleaning patio air conditioners and portable units, with no fumes that would bother outdoor diners or neighbors.
Is the formula weather-resistant enough to be stored in a garage or service truck between jobs?
Yes. The non-flammable, non-caustic formula is stable across a wide temperature range and is suitable for storage in a garage, shed, or service truck between outdoor coil cleaning jobs.
Can I use this to clean the outdoor unit of a heat pump in cold weather?
Yes, as long as the coil is above freezing and the product is allowed to dwell before the rinse, it works in cool weather; for freezing conditions, schedule cleaning for a milder day so the rinse water does not refreeze on the coil.
Will the foam cling to a vertical outdoor condenser coil without blowing off in the wind?
Yes. The cling-time foam is engineered to adhere to vertical and overhead coil surfaces, so it stays in place on outdoor condenser coils even in light breeze conditions.
Is this product a good choice for cleaning the condenser on a restaurant's rooftop AC unit?
Yes. The non-flammable, NSF-registered formula is a strong match for restaurant rooftop AC condenser coils that are routinely fouled by kitchen exhaust and airborne cooking oils.
Will the cleaner hold up in a pump sprayer during long outdoor HVAC routes?
Yes. The chemistry is stable in standard pump-up and pressurized sprayers commonly used by HVAC technicians running outdoor service routes, and it does not separate or clog under normal use.
Is the gallon size easy to transport to a rooftop job site from a service van?
Yes. The 128 fl oz gallon is sized to fit standard service van shelving and most rooftop job site carts, making it easy to transport up ladders or service elevators to a rooftop unit.
Can I use this to clean the coils on an outdoor walk-in cooler at a restaurant?
Yes. The NSF K5 degreaser registration makes it approved for use on commercial refrigeration evaporator coils, including outdoor walk-in cooler units adjacent to food prep areas.
Will the unscented formula bother guests at an outdoor dining event if I clean a nearby AC unit?
No. The unscented, fume-free formula does not release noticeable odors, so it will not affect guests at an outdoor dining event if applied to a nearby AC or refrigeration unit during service.
How does this outdoor coil cleaner compare to a standard garden hose rinse for a dirty condenser?
A garden hose rinse only removes loose surface debris, while the foaming degreaser actively breaks down the grease, oil, and biofilm that a hose cannot touch, restoring airflow and efficiency the rinse alone cannot.
How does this compare to a bleach solution for cleaning outdoor condenser coils?
Bleach is corrosive to aluminum coil fins, produces harsh fumes, and offers limited degreasing action, while this foaming non-caustic formula lifts grease without corroding fins and is safer for the technician and surrounding landscaping.
Is this a better outdoor option than a pressure washer for routine condenser maintenance?
Yes, for routine maintenance. Pressure washers can bend delicate aluminum fins and drive water into electrical components, while the foam application cleans the soil off the fin surfaces without mechanical damage or water intrusion.
Will the foam hold on a coil that is in direct summer sun on a rooftop?
Yes. The cling-time foam is designed to maintain structure on hot, sun-exposed rooftop coils long enough for the surfactant chemistry to break down the soil before rinse.
Can I rinse the foam off with a standard garden hose after the dwell time?
Yes. A standard garden hose rinse is sufficient to remove the foam and dissolved soil from an outdoor condenser coil after the recommended dwell time, with no special equipment required.
Will the formula freeze or separate if I leave the gallon in an unheated garage over winter?
The product should be stored above freezing for best performance; if a jug does freeze, allow it to thaw completely and shake well before use, and the chemistry will return to its original performance.
How do I use Simple Green Foaming Coil Cleaner on an outdoor condenser coil?
Disconnect power to the unit, apply the foam directly to the coil surface, allow the recommended dwell time for the foam to break down soil, and rinse thoroughly with a garden hose from the inside out. Restore power only after the coil is dry.
How do I use it on an indoor evaporator coil?
Disconnect power, apply the foam to the coil surface, allow dwell time, and let the self-rinsing condensate action carry the dissolved soil down the condensate drain. No separate rinse step is required on condensate-producing coils.
How do I dilute the concentrate if I want to use it in a pump-up sprayer?
Refer to the product label for the current dilution chart, as ratios vary by application. For light soil, the product is often used at a lower concentration, while heavy grease and oil may call for a stronger mix or straight application.
Is this product compatible with aluminum and copper coil fins?
Yes. The non-caustic formula is safe for use on aluminum fins and copper refrigerant coils, unlike acid-based coil cleaners which can corrode both metals.
Will it work with my existing pump-up foam sprayer or does it require a special applicator?
It works with most standard pump-up and pressurized foam sprayers commonly used in HVAC service. Use a foaming nozzle tip for best cling on vertical coil surfaces.
What is included when I order the gallon versus the 5-gallon pail?
The gallon ships as a single 128 fl oz jug. The 5-gallon option ships as a 640 fl oz drum. Spray-ready 20 oz sizes ship as individual cans. Multi-pack bundles include the number of gallons listed in the pack title.
Is Simple Green Foaming Coil Cleaner safe to use around pets and children during application?
The non-caustic, fume-free formula is significantly safer than acid or alkaline coil cleaners, and when used as directed with normal ventilation, it does not pose unusual risk to pets or children in the home.
Will the product damage my HVAC system if some foaming residue drips onto the drain pan?
No. The formula is designed to flow safely through the condensate drain pan and drain line, and at recommended use rates it will not harm the pan, the drain line, or the air handler cabinet.
What is the difference between a coil cleaner and a general-purpose degreaser?
A coil cleaner is formulated to be safe on delicate aluminum fins and copper tubing while still lifting grease, oil, and grime, and is often NSF registered for incidental food contact areas. A general-purpose degreaser may be too harsh for fin surfaces and may not carry food-safe registration.
