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.
Pro HD is heavy-duty enough to maintain landscaping equipment and heavy machinery, but gentle enough for use on stove tops, ovens, grills, range hoods, vents, BBQs, refrigerators, and more.
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.
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
Will one gallon of this concentrate actually speed up my jobsite cleanup compared to using multiple specialty cleaners?
Yes. Because a single gallon of Simple Green Pro HD cuts grease, oil, carbon, and grime across engines, tools, floors, and equipment, most crews can replace several bottles of dedicated degreaser, floor stripper, and parts-wash fluid with one product. That means fewer trips to the truck, fewer SKUs to stock, and faster end-of-day washdowns so your team can clock out on time.
Does the concentrated formula help me finish pressure-washing jobs in fewer passes?
It does. The professional-grade dilution is engineered to break the bond of road film, grease, and mildew in a single pass when mixed correctly, so contractors spend less time re-spraying the same section. For detailers and fleet operators, that translates directly into more vehicles turned out per shift.
Can my crew dilute it for the specific job so we are not wasting product on light cleaning?
Absolutely. Simple Green Pro HD is built to be dialed in: heavier mixes for engine degreasing and parts washing, lighter mixes for routine floor and wall cleaning. That flexibility lets you control cost per job and keep productivity high without over-using concentrate on quick tasks.
Will using one product across the shop really save my team setup and training time?
Yes. When the same bottle handles the parts washer, the pressure washer, the floor mop bucket, and the wipe-down station, new hires only need to learn one dilution chart. That shortens onboarding and reduces the cross-contamination mistakes that come from juggling multiple specialty chemicals.
Does the 1-gallon size fit standard shop dispensing systems so we can keep workflow fast?
The bottle is sized to pour cleanly into most shop pumps, proportioners, and dilution bottles. Many contractors and detailers decant it into labeled spray bottles at the workstation, which keeps the concentrate off the floor and lets techs grab and go without interrupting their workflow.
Is this a smart bulk buy for a working detail shop that runs through cleaner every week?
For high-volume detailers, mechanics, and contractors, a single heavy-duty concentrate is usually more cost-effective per ounce than buying several smaller specialty bottles. It also frees up shelf and van space, which matters when every cubic inch of the truck is dedicated to billable tools.
Can I use it to speed up prep work on renovation and punch-list jobs?
Yes. Paint prep, drywall dust, adhesive residue, and construction film all come off faster when you can switch to one trusted cleaner instead of trial-and-error with multiple products. That keeps punch lists moving and protects your reputation for clean handoffs.
Will it help my team get vehicles, floors, and equipment done in the same shift without switching products?
That is exactly the use case it was built for. Crews can move from a greasy engine bay to a concrete shop floor to a fleet van exterior using the same concentrate at different dilutions, eliminating the downtime that comes with rinsing out sprayers and swapping chemicals.
How does it compare to using a separate citrus degreaser and a separate alkaline cleaner on the job?
Most pros who try it replace two or three specialty bottles with Simple Green Pro HD. You trade the narrow strength of a citrus product or a high-pH stripper for a single, balanced concentrate that handles light and heavy soils. The net result is a faster truck pack, simpler inventory, and fewer chemical reactions to worry about on mixed-material jobs.
Is the concentration strong enough to handle production-volume cleaning, not just occasional use?
Yes. This is a professional-grade concentrate designed for daily use in body shops, detail bays, commercial kitchens, and contractor crews. A little goes a long way, so even shops that wash multiple vehicles or scrub floors daily find a gallon stretches further than expected.
I am worried one cleaner will not be strong enough for my toughest grease jobs. Will it actually cut carbon and baked-on oil?
That is the most common hesitation from crews switching from dedicated engine degreasers. In practice, Simple Green Pro HD is formulated to break down petroleum, carbon, and food grease at recommended dilutions, and you can always step up the mix ratio for heavily soiled engine parts and shop equipment without switching products.
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.
