Small changes in product size & weight lead to lower carbon emissions.
We created Compact by Design to identify products that, while they may not always look very different, have a more efficient design. With the removal of excess air and water, products require less packaging and become more efficient to ship. At scale, these small differences in product size and weight lead to significant carbon emission reductions.

Frequently Asked Questions
Is this formula truly non-corrosive and safe to use on aluminum parts and polished metal?
Yes. Simple Green Pro HD is specifically engineered to be non-corrosive on aluminum, stainless steel, and other sensitive metals that traditional acid or high-alkaline degreasers can etch. That makes it a safer choice for engine components, aircraft-style fittings, food-service equipment, and polished trim where surface damage is not acceptable.
Since it is unscented and biodegradable, is it safe to use around food prep areas and indoor air spaces?
The unscented, biodegradable formulation is a major reason commercial kitchens, schools, and healthcare facilities choose it. There are no overpowering fragrances to linger in dining areas, and the formula is designed to rinse clean, which helps teams meet sanitation standards without filling the building with chemical odor.
Is it compliant with Prop 65 and other professional safety standards I need to meet on the job?
Yes. Simple Green Pro HD is Prop 65 compliant and is widely used in regulated environments including commercial kitchens, government facilities, and schools. Always follow the label directions and your site-specific PPE policy, but the formulation itself is built to meet professional safety expectations.
Will it produce harsh fumes that could bother my staff or customers during indoor use?
The unscented, low-odor formula was designed for indoor and enclosed-space use. Compared to solvent-based degreasers, ammonia cleaners, or acid descalers, it produces far less airborne irritation, which makes it easier on staff who are cleaning every shift and on customers or occupants in nearby spaces.
Does the concentrate pose a storage or handling risk compared to flammable solvents?
It is a water-based concentrate, so it does not carry the same flammability, shipping, and storage restrictions as petroleum solvents or alcohol-based cleaners. That simplifies the safety data sheet, reduces storage cabinet requirements, and lowers the overall hazard profile in shops, vans, and maintenance closets.
Is this a safer everyday cleaner for my auto shop than the solvent parts-wash fluid I use now?
For many shops, yes. Solvent-based parts washer fluids are effective but come with flammability, fumes, and disposal concerns. Simple Green Pro HD, used in compatible parts washer systems, gives you heavy-duty cleaning power with a more worker-friendly profile, which is a big reason mechanics switch when they are ready to upgrade their safety program.
I run a commercial kitchen and my staff is sensitive to chemicals. Is this gentle enough for daily use?
The unscented, biodegradable, non-corrosive profile makes it well suited to daily kitchen cleaning on floors, equipment, and prep surfaces. Staff who react to strong fragrances or harsh degreasers typically tolerate it much better, while you still get the grease-cutting power a busy line demands.
Will using it in a pressure washer create mist that is unsafe to breathe around my crew?
Like any pressure-washing detergent, you should follow basic precautions, but the low-fume, water-based formula produces far less respiratory irritation than solvent or acid-based wash chemicals. With sensible ventilation and standard PPE, it is a noticeably milder option for crews pressure-washing indoors or in partially enclosed bays.
Is it safer for my family and pets than the harsh degreaser I currently use in the garage?
For home use, the unscented, non-corrosive, biodegradable formula is a much friendlier choice than solvent or acid-based garage degreasers. It is still a concentrate that should be stored properly and kept out of reach of children and pets, but you will not be dealing with harsh fumes etching the garage air every time you clean.
How does it compare to a typical bleach or ammonia-based cleaner from a safety standpoint?
Compared to bleach or ammonia, Simple Green Pro HD is non-corrosive, unscented, and biodegradable, and it will not release chlorine or strong ammonia fumes. For routine degreasing where bleach or ammonia would be overkill, it is a substantially safer daily option for staff, surfaces, and indoor air quality.
I am worried about long-term worker exposure. Is this formula something my team can safely use every day?
Daily, professional use is exactly what it was designed for, which is why it is a staple in detail shops, kitchens, and maintenance departments. As with any concentrate, following the recommended dilutions, wearing the PPE listed on the label, and providing good ventilation are the keys to keeping long-term exposure low.
How do I dilute Simple Green Pro HD for different cleaning jobs?
Dilution depends on the job. For heavy degreasing of engines, parts, and shop equipment, use the concentrate or a strong dilution such as 1:1 to 1:10 with water. For pressure washer exterior work, 1:10 to 1:20 is typical. For routine floor and wall cleaning, light dilution around 1:30 works well. Always start with the recommended ratio on the label and adjust up for tougher soils and down for lighter messes.
Can I use it in a pressure washer, parts washer, and ultrasonic cleaner?
Yes. Simple Green Pro HD is designed to be compatible with pressure washer injection systems, recirculating parts washers, and ultrasonic cleaning tanks. For ultrasonic use, follow the equipment manufacturer guidance on temperature and dilution, and rinse parts after cleaning to remove any residue before reassembly.
What is the best way to apply it for greasy engine bays and automotive parts?
Spray or brush the diluted concentrate onto a cool engine or part, let it dwell for a minute or two to break down grease, agitate with a brush on heavy buildup, then rinse thoroughly with water or a pressure washer. For heavily carbon-fouled parts, use a stronger dilution and repeat as needed.
Is it safe to use on carpet, upholstery, and other interior fabrics?
It can be used on many interior fabrics at a light dilution for spot treatment of grease and oil stains. Always test in an inconspicuous area first, avoid soaking the material, and blot or extract rather than scrubbing aggressively. For delicate or natural fiber fabrics, consult the manufacturer care guide first.
Will it damage aluminum, chrome, stainless steel, or painted surfaces?
The formula is non-corrosive and is engineered to be safe on aluminum, chrome, stainless steel, and cured painted surfaces when used as directed. Avoid letting the concentrate dry on hot surfaces in direct sun, and rinse thoroughly after the dwell time. For unknown coatings, always spot test first.
What comes in the box when I order the 1-gallon version, and what do I need to buy separately?
You receive one 1-gallon bottle of concentrated Simple Green Pro HD Heavy Duty Cleaner. The bottle has a standard cap that you can pour from, but for the best experience you may want to pick up a shop pump, a labeled spray bottle, or a dilution jug, none of which are included.
How should I store the concentrate to keep it effective and safe?
Store the bottle sealed in a cool, dry area out of direct sunlight, and keep it out of reach of children and pets. Avoid letting the product freeze or sit in extreme heat for long periods, and keep the cap tightly closed to prevent evaporation, which can change the dilution strength.
Is it safe to use around septic systems and standard drain plumbing?
The biodegradable, water-based formula is generally safe for septic systems and standard plumbing when used at recommended dilutions and flushed with plenty of water. Avoid pouring undiluted concentrate directly into a septic system in large volumes, and follow any local guidelines for commercial waste disposal.
What is the difference between a concentrated degreaser like this and a ready-to-use all-purpose cleaner?
A concentrated degreaser is a professional-strength product you dilute yourself to match the job, which gives you far more cleaning power per ounce and much better cost control. A ready-to-use all-purpose cleaner is pre-diluted for light everyday messes and is convenient but more expensive per use and weaker on heavy grease, oil, and carbon.
