Simple Green Foaming Cleaners: Matching the Formula to the Mess

Best for
Everyday grime on desks, walls and floors

The Simple Green All-Purpose Foaming Aerosol Cleaner comes as two 20 oz cans and is the generalist in this lineup. The description says the foam clings to vertical surfaces and hard-to-reach spaces, and the can even sprays upside down. It is listed for any washable surface, including counters, carpets, floors, walls, fabric, equipment and vehicles, and it removes grease, dirt and grime while deodorizing.

For a gaming or streaming setup, that means the sticky ring under a snack bowl, a scuffed wall behind a desk, a grimy chair base or a greasy spot on a rug. Foam gives you more control than a runny spray around furniture, though you should still keep any cleaner away from live electronics and wipe rather than soak. The listing also shows a biodegradable material feature. If you want the regular liquid version instead, our Simple Green cleaner guide covers the non-aerosol range.

• Foam clings to vertical surfaces
• Sprays upside down
• For any washable surface
• Two 20 oz cans

The Simple Green Foaming Coil Cleaner 20oz aerosol three-pack is the specialist for coils. The description calls it a professional-strength formula that penetrates to remove dirt and grease that can cause clogs, impede heat transfer or hold back equipment performance. The foam is non-caustic and non-flammable, it clings to hard-to-reach areas, and it is self-rinsing on condensate-producing coils.

That self-rinsing point matters: an evaporator coil that produces condensate will carry the loosened dirt away with the water it already makes, so you do not have to hose it off. Dirty coils make an air conditioner work harder, and a room full of gaming PCs and consoles is exactly the kind of space where you want AC running efficiently. The formula has no added color or scent and is NSF registered C1 and K5. Three cans suit someone with more than one unit or a yearly cleaning routine.

• Non-caustic, non-flammable foam
• Self-rinsing on condensate-producing coils
• No added color or scent
• NSF registered C1 and K5

The Simple Green Foaming Coil Cleaner in the 128 fl oz gallon uses the same coil formula and description as the aerosol pack. The difference is volume and format. The description mentions that the foam works when sprayed under pressure, but the listing does not specify whether a sprayer is included, so plan to use your own suitable sprayer.

This size is aimed at technicians, landlords or anyone maintaining several condensers, evaporators or refrigeration units. For a single window or split unit at home, a gallon is more than most people will use, and the 32 fl oz bottle or the aerosol cans are easier to handle.

The Simple Green Foaming Coil Cleaner in the 32 fl oz size is the middle option. Its description is identical to the other two coil listings: professional-strength, non-caustic, non-flammable, self-rinsing on condensate-producing coils, no added color or scent, and NSF registered C1 and K5.

The listing does not say whether it comes with a trigger sprayer or needs a separate pump sprayer, so check the product images before buying. For one home air conditioner that you clean once or twice a year, this is the sensible size. If you prefer point-and-spray convenience, the 20 oz aerosol pack is simpler to use.

Best for
Riders degreasing bikes

The Simple Green Bike 20oz Aerosol Cleaner and Degreaser comes as a two-pack of 20 oz cans. The listing gives only its title, so the one firm fact is its purpose: cleaning and degreasing bikes.

The listing does not specify whether it foams, which bike surfaces or components it is intended for, or whether it needs rinsing. For riders who want a product named for bike care rather than a general cleaner, it is the obvious pick, but check the can’s own instructions before using it on brakes or finished parts. If you mainly need a degreaser for a garage bench, the all-purpose aerosol or Pro HD is better documented.

Best for
Heavy grease on tools and machinery

The Simple Green Pro HD Heavy Duty Cleaner Concentrate is a 1 gallon bottle, and it is worth being clear: the listing describes a liquid concentrate, not a foaming aerosol. It is included here because it is the brand’s heavy-duty option for grease that the lighter cleaners struggle with, and it is a common Simple Green degreaser for garages and workshops.

The listing calls it non-corrosive and professional grade, for floors, walls, industrial equipment, appliances, automotive and recreational vehicles, commercial kitchens and baths, pressure washing, parts washing and ultrasonic cleaning. It is safe on metal surfaces, unscented and odor-free, and listed as biodegradable. It is also labeled as a Prop 65 product, so read the label and handle it accordingly. Choose it for engine bays, machinery and tools; skip it for quick desk cleanups, where the foaming aerosol is easier. For lighter degreasing in the home, a ready-to-use degreaser spray is another option.

• Concentrated, 128 fl oz
• Safe on metal, non-corrosive
• Pressure washing, parts washing and ultrasonic use
• Unscented and odor-free
