Simple Green Pro HD Heavy-Duty Cleaner is a professional grade cleaner and degreaser that breaks down tough grease, eliminates grime, and removes stains on a wide variety of surfaces including engines, car exteriors, machinery, floors, walls, and more. It is non-corrosive to metals, non-degrading to plastics, and clean rinsing.

The cost-effective concentrate can be custom diluted for specific cleaning jobs, and can be used in pressure washers, carpet cleaners, floor scrubbers, ultrasonics, dip tanks, and other cleaning equipment. The water-based cleaner provides a safer alternative to solvents and other harsh cleaning chemicals without sacrificing performance.

Frequently Asked Questions
Since it is unscented, is it a good choice for households with allergies or chemical sensitivities?
Yes. The unscented, biodegradable formula is one of the main reasons it is chosen for scent-sensitive homes, asthma households, and allergy-conscious families. There are no masking fragrances or heavy perfumes to trigger reactions, which is a meaningful upgrade over heavily fragranced all-purpose cleaners.
Is it safe to use in my home around kids and pets when I clean the garage or entryway?
The non-corrosive, water-based formula is significantly gentler than solvent or acid-based alternatives, which is why so many parents and pet owners reach for it for garage, mudroom, and entryway messes. As with any cleaner, keep the concentrate stored out of reach and let surfaces dry before kids and pets have access, but you will not be filling your home with harsh fumes.
Can I use it on surfaces my family touches every day, like kitchen floors and appliance exteriors?
Absolutely. The same concentrate used on commercial kitchen floors is safe for residential kitchen and appliance cleaning at the recommended dilutions. It cuts the everyday grease that builds up around stoves, range hoods, and trash cans without leaving heavy fragrance or sticky residue behind.
Is the formula something a health-conscious homeowner can feel good about using?
For ingredient-conscious buyers, the biodegradable, non-corrosive, unscented profile is a real differentiator. There are no harsh acids, no solvents, and no heavy synthetic fragrance, so you can deep-clean a greasy garage or a kitchen floor without worrying about what is being left behind on surfaces your family uses every day.
Will it help me keep a calm, low-irritation home environment while still tackling heavy messes?
Yes. The unscented, low-fume formula means you can deep clean on a weekday evening without overwhelming the home with chemical smell, which matters for people who run mindfulness routines, work from home, or have little ones on strict sleep schedules. You get the clean without the sensory overload.
Is this a good cleaner to use in a home gym or wellness space where I sweat and breathe heavily?
For home gyms, yoga rooms, and garage workout spaces, the unscented, low-residue formula is a thoughtful choice. It cleans rubber flooring, mats, and equipment without leaving behind heavy fragrance or chemical film that you would be breathing in during your next session.
Can I use it to clean my hobby or craft space without worrying about fumes?
Yes. Hobby spaces tend to have poor ventilation, which is exactly where an unscented, water-based concentrate shines. It cuts the grease and dust from woodworking, ceramics, model-building, and other crafts without adding another layer of chemical odor to the room.
Is it a good choice for households that prioritize eco-friendly and biodegradable products?
It is a strong fit. The biodegradable formula breaks down after use rather than persisting in the environment, and the concentrate format means less plastic waste than buying multiple specialty spray bottles. For eco-minded buyers, that is a meaningful upgrade over traditional petroleum-based degreasers.
How does it compare to typical green-labeled natural cleaners when I need real degreasing power?
Most plant-based or natural cleaners handle light messes well but struggle with engine grease, kitchen buildup, and renovation grime. Simple Green Pro HD bridges the gap: biodegradable and unscented, but with the professional strength to actually finish the job, which is the balance many wellness-focused buyers are looking for.
Will it leave any chemical residue that could affect my indoor air quality after cleaning?
When used at the recommended dilutions and rinsed where appropriate, it leaves surfaces clean without a chemical film. That matters for households focused on indoor air quality, because residue from heavy cleaners can off-gas for hours; this formula is designed to rinse clean and leave nothing behind but a clean surface.
I am worried it will smell like a harsh industrial chemical in my home. Is the scent really neutral?
It is genuinely unscented, with no added fragrance to mask the base formula. Compared to bleach, ammonia, citrus solvent degreasers, or heavily perfumed all-purpose sprays, the difference in how your home smells during and after cleaning is significant, and that is a big reason scent-sensitive households keep coming back to it.
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.
