I have spent years cleaning everything from greasy garage floors to delicate boat hulls, testing dozens of formulas to see what actually cuts through grime. Recently, I put Release Cleaner and Simple Green head-to-head on some of the toughest soot, oil, and daily messes I could find. This comparison breaks down my hands-on experience with both so you can choose the right one for your cleaning arsenal.
Release All Surface Cleaner & Degreaser 32 Oz Spray Bottle
When I first picked up the Release All Surface Cleaner & Degreaser, I wanted to see if its industrial credentials held up in real-world scenarios. This specialized formula is completely fragrance-free and contains no phosphates, making it a great choice for sensitive environments. It is designed to be safe on virtually all surfaces, which means you do not have to worry about damaging delicate materials. During my testing, I found it incredibly effective at breaking down tenacious soils, grease, oil, carbon, and soot. Because it meets Florida’s strict requirements for cleaning boats in harbors, you can use it near waterways with peace of mind.

Simple Green All Purpose Cleaner Concentrate 64 Fl Oz
Simple Green All Purpose Cleaner Concentrate has been a staple in my garage for as long as I can remember. This highly concentrated formula allows you to custom-blend your cleaning strength, meaning you can dilute it for light countertops or use it full strength on oil spills. It carries the EPA Safer Choice certification, which gives me peace of mind when working around pets or children. The formula easily handles dirt, grease, and stubborn stains across a wide variety of surfaces including carpets, fabric, concrete, and vehicle engines. When you finish scrubbing, it leaves behind a very recognizable, refreshing sassafras scent that masks heavy odors. This massive bottle offers incredible cost savings for homeowners, mechanics, and small business owners alike.

release cleaner vs simple green: Key Differences That Matter
Performance Comparison
When it comes to raw power on specific types of grime, these two products behave very differently. Release Cleaner is formulated specifically for industrial soot, baked-on carbon, and stubborn petroleum oils. It dissolves exhaust stains on boat hulls and soot on engine parts almost on contact, without requiring much elbow grease. Simple Green is a fantastic generalist. It easily tackles kitchen grease, dusty shop floors, and fabric stains, but it requires significantly more scrubbing on heavy carbon build-up than Release.
Price and Value Analysis
There is a stark contrast in value here. Simple Green comes as a 64-ounce concentrate. You can stretch a single bottle into dozens of spray bottles of light-duty cleaner, making it incredibly cheap per fluid ounce. Release Cleaner comes in a ready-to-use 32-ounce spray bottle. You are paying a premium for a specialized, pre-mixed chemical formula that is ready to go right out of the box, which makes it much more expensive for bulk cleaning.
Material Compatibility and Build Quality
The physical spray mechanism on the Release bottle is sturdy, delivering a fine, consistent mist that clings well to vertical surfaces. Since Simple Green is sold as a refill concentrate, you will need to supply your own spray bottle and mixing container. The chemical formulation of Release meets strict aerospace and marine standards, meaning its chemical purity and non-corrosive properties are highly controlled. Simple Green is chemically stable but relies on a water-based formula that can occasionally corrode bare aluminum if left to dry without rinsing.
User Experience Differences
The most immediate difference when using these products is the scent. Release is completely fragrance-free, making it comfortable to use in tight boat cabins or closed garages. Simple Green fills the entire room with its signature sassafras licorice scent, which some people love and others find overwhelming. Additionally, Release is a spray-and-wipe solution, whereas Simple Green often requires a thorough water rinse to prevent a sticky film or green tint from drying on the surface.
Which Should You Choose?
If you are dealing with marine soot, black streaks on fiberglass, or aerospace-grade metals, you should buy Release Cleaner. It meets specialized environmental and material specifications that Simple Green cannot match.
If you need an affordable, all-purpose solution for everyday household spills, pet accidents, and workshop maintenance, the winner of the release cleaner vs simple green debate is clearly Simple Green. Its concentrated nature saves you money and lets you customize your cleaning power for carpets, kitchens, and cars.
For specialized, high-stakes cleaning where surface damage is not an option and carbon is the enemy, invest in Release. For general household and garage chores where value and versatility reign supreme, keep a bottle of Simple Green concentrate on your shelf.
