Alkaline aqueous solutions remove grease, coolants, cutting oils, shop dirt, fingerprints, cosmoline, petroleum and some water-soluble paints. They are also used with all types of liquid processes, e.g., sprays, ultrasonic, immersion and power washers. These solutions can clean to very high levels, with good filtration and rinsing. Cost per gallon is generally less than for semi-aqueous cleaners.
One should never assume that aqueous solutions can be disposed of down the drain. Your local water treatment authority or publicly owned treatment works (POTW) will have information on treatment and disposal of these cleaners.
Simple Green has also developed break-through water based cleaners that are safe for use on metals, plastics, rubber and high tech alloys. Extreme Simple Green Aircraft & Precision Cleaner, Pro Series Simple Green Automotive Cleaner, and Simple Green Pro HD are available on both the industrial and retail markets, respectively. These products were initially developed for the aircraft industry and extensive testing shows that they are safe and effective on a variety of metals and other sensitive surfaces even in the most extreme circumstances.
Simple Green Stainless Steel One Step Cleaner & Polish is another option for cleaning polished aluminum. This product is designed for light duty metal cleaning and polishing.
During our 40 year history, Simple Green All-Purpose Cleaner has been used all over the world to save lives of birds and mammals caught in oil spills and chemical lagoons, because it enables them to be cleaned and then returned to the wild with minimal stress and no ill effects. Simple Green has also been used to maintain safe and clean environments for mammals, birds, and fish that are temporary guests of veterinary clinics and wildlife rehabilitation centers (such as the World Bird Sanctuary, The Marine Mammal Stranding Center, and the Dolphin Rescue Center,) as well as for those animals that are permanent residents of zoos, aviaries, and aquatic centers (the National Zoo, Shedd Aquarium, Wellington Zoo, and the Monterey Bay Aquarium are a few examples.)
Simple Green products that are sold in the USA are assembled 100% in the USA at the facilities listed above. We utilize USA-made ingredients and source USA-made components for our products. If a particular ingredient is not viable for purchase in the USA, due to unforeseen acts of nature or force majeure, we have on occasion been forced to source it from a trade-friendly country. We are of the opinion that in those rare occurrences, it has been an insignificant portion to the overall product composition; that, we can maintain "All or virtually all" US origin product. As soon as normal US sourcing is made available, off-shore components are replaced with domestic.
We make this claim on a reasonable belief - and rely on - that as we negotiate our manufacturing and supply chain sources; we are reaffirming that those sources are of domestic origin. This good faith reliance has allowed Sunshine Makers, Inc. to faithfully say "Made in the USA" for over 35 years.
Simple Green does not use citrus ingredients as cleaning agents within our products. However, some of the fragrances in Simple Green products and several of the essential oil blends for Simple Green Naturals product contain tiny amounts of citrus oils as scent agents.
A word of caution: when adding foreign material into Simple Green All-Purpose Cleaner, be aware that biodegradability, toxicity and disposal issues need to be addressed by the additive manufacturer.

The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) are currently tracking an H1N1 flu outbreak that has caused infections in humans in the United States, Mexico, Canada and other countries.
EPA registers pesticide products, including disinfectants. As part of the registration process, EPA evaluates the product efficacy to make sure the public health label claims are accurate. Currently, over 500 disinfectant products are registered for use on hard, non-porous surfaces against influenza A viruses. EPA believes, based on available scientific information, that the currently registered influenza A virus products will be effective against the 2009-H1N1 flu strain and other influenza A virus strains on hard, non-porous surfaces. For safe and effective use of these products, always follow label instructions for these products, paying special attention to the product's dilution rate (if applicable) and contact time.
Choose a product whose label states that it is effective against "Influenza A virus" and lists your specific site of concern, such as: farm premises, hospitals and other healthcare facilities, schools, offices or homes. These products are widely available and can be purchased at home maintenance/repair stores and industrial/institutional distributors, among others.
As the CDC stresses, your first line of defense is to wash your hands frequently with soap and water or use an alcohol-based cleaner. Registered disinfectant products are for use on hard, non-porous surfaces, such as door knobs, handles, tables, floors, etc. EPA emphasizes that these products are not to be used on the skin or to be taken orally.
Simple Green All-Purpose Cleaner does not contain chlorine (bleach), ammonia, formaldehyde, phosphates or petroleum distillates.
A Note about Ingredients: In late 2012, Sunshine Makers, Inc. implemented a 4 year reformulation project, and changed the formula of Simple Green to what is listed above. This was done to comply with 2013 California air quality regulations. We conducted testing to confirm that the new formulation is every bit as efficacious as the prior formula, and that it is just as safe for the user and the environment. For more information about this, please see the 2013 MSDS, and test data at https://simplegreen.com/claims/.
Care should be taken when spraying Simple Green All-Purpose Cleaner above the level of one's head, or using mechanical applicators that create mist (pressure sprayers, steam cleaners, etc.) Additionally, Simple Green products are sold in spray bottles that create a coarse droplet spray that is not easily inhaled. If using a spray bottle other than a Simple Green spray bottle, take care not to breathe in any mist. Use Simple Green products in a well-ventilated area or, in more extreme cases or cases of impaired lung condition, use of a fiber painter's mask (found in hardware and home improvement stores) will greatly reduce the risk of inhalation problems.
This makes Simple Green products non-deionizing. Crystal Simple Green Industrial Cleaner & Degreaser are suitable for use in clean room cleaning applications, in nuclear submarine cleaning, and in other circumstances in which electrical stability of a cleaning product is imperative.
Simple Green All-Purpose Cleaner is not recommended for use in High Effeciency (HE) machines. We do also offer a specially formulated Laundry Detergent.
Simple Green's answer to MRSA is Simple Green d Pro 3 and Simple Green d Pro 5. For more information about these products, including contact information for those industrial and institutional distributors carrying it in your area, please call Customer Relations at 800-228-0709.
In reality, toxicity is relative. Everything is toxic in large enough quantities. A person could consume enough milk, chocolate or even water to cause death.
Simple Green brokers Parts washers with 30 gallon, 60 gallon, and 80 gallon capacity. Simple Green parts washers are made of thermoplastic, with a recirculating pump, heater and replaceable filter cartridge. Recommended temperature is to remain below 120°F. For more information on parts washers, go to the Family of Industrial Equipment page.
pH is an important factor to consider when choosing or recommending cleaners or degreasers. Cleaners at both ends of the scale (14 & 0) can be effective cleaners, however they are more likely to be environmentally hazardous or present serious health hazards. The challenge in choosing a product is finding a balance of both safety and effectiveness. Simple Green All-Purpose Cleaner meets both of these qualifications.
Gallon containers and smaller are packaged in either PETE or HDPE type plastic and are readily recyclable nationwide. Trigger Sprayer tops are made of 80% Polypropylene and 20% HDPE and are recyclable but will only be accepted at certain recycling centers. To find a recycling facility near you we suggest looking at Earth911 will only be accepted as certain recycling centers.
DRUMS & PAILS
Simple Green ships drums of product all around the USA (and internationally) - mainly to industrial & institutional distributors. We then do not have data about where distributors ship them. Therefore, there is no practical or financially feasible way for our company to offer a drum return program. Further, it is not environmentally correct to ship empty drums back from a multitude of locations when there are facilities around the country that will take them and recycle them locally.
- We recommend that end-users utilize Earth911 to find local recycling sites that will take #2 HDPE colored plastic (which our drums are made of.) HDPE is readily recycled around the country and the Earth911 site is super easy to use.
- Another method of getting drums into the recycling stream is to check with a waste hauler to see if the drums can be removed from facilities along with other recyclable trash. Here in Huntington Beach, manufacturers can have HDPE drums removed along with other solid waste and our city refuse collection company sorts out the recyclable materials.
- One other suggestion is to check and see if there is a rain-water program in your city. Because Simple Green is non-toxic and rinses easily, our drums can be easily utilized in rain-water collection systems. www.harvesth2o.com. This site lists many programs around the country. If there is an active rain-water collection program in the locale of the facility with the empty drums, this can often be a great synergy between a facility and its community.
A black-light is a handy tool for finding urine spots when they can be smelled but are not visible to the naked eye. Your first step is to darken the room as much as possible.
Dried urine has a signature dull yellow glow. This will help you tell it apart from other things that glow such as detergents (often glow bright white or blueish-white) and lint (which glows very bright white.) Simple Green Pet Stain & Odor Remover does not fluoresce under black-light. Another characteristic of a pet urine stain is a puddle, stream, or spray shape to the stain. Cats & dogs often urinate in room corners or at the base of furniture. If your pet is a cat, also check baseboards and low wall areas as these are often additional areas where cats spray urine. Because urine may seep into carpet pads or underlying floor, you may want to lift carpet where you can and check underneath it, too.
Once the area has been cleaned, you may still see fluorescence if the urine has interacted with the carpet dye, or if more urine has drawn up from the padding into the carpet fibers. Even though the stain is no longer visible in normal light and the smell is gone, the area can still show residual fluorescence under black-light. Even if you keep treating the same spot repeatedly, it is possible that you could still see residual fluorescence. So, if the visible stain and the smell are gone upon first or second treatment, the objective of the product has been met.
Simple Green Pet Stain & Odor Remover works via a combination of biological action and through the surfactant in the product. The surfactant will handle 99% of the color of the stain. There are a few pet foods that contain actual dyes that can chemically interact with carpet dyes and form a non-biological stain on carpet or fabric that simply cannot be reversed. (Think of pouring a little bleach onto a dark fabric or carpet. The only way to cover the white bleached spot is to re-dye the fabric or carpet - and even then you might still see a color difference at the bleached area.)
The biological component of Simple Green Pet Stain & Odor Remover is a combination of several different non-harmful bacteria that produce enzymes when they are in the presence of organic soil (food) and moisture (water). Soaking a urine spot with Simple Green Pet Stain & Odor Remover unleashes the bacteria to start making enzymes to convert organic soils into digestible food for the bacteria. If the spot dries out before all organics have been consumed, some of the urine salts can still remain. It is recommended that if the stain is still visible, or the smell remains, to first wet the area with plain water and allow the bacteria to continue doing their work. If stain and smell still remain, a second application of the product is warranted.
It is much easier to eliminate urine on hard, non-absorbent surfaces such as tile floors or painted baseboards. One exception may be hardwood floors. If urine sits for too long on some hardwoods, the cellulose in the wood can actually become burned. If that happens, no cleaner will eliminate the black mark that results. Only refinishing will resolve that problem.
Soft, absorbent surfaces can be more difficult and involve repeated applications, the use of extraction equipment, applying and extraction of carpet fibers, carpet backing, carpet padding, and even the floor below. Therefore, eliminating ALL fluorescence is often not practical and is just too costly in time, money, and effort. Removal of the visible stain and of the smell is the achievement of success.
Use a black-light to locate urine stains, treat them with Simple Green Pet Stain & Odor Remover, and then enjoy the fresh, clean results!
Whether steam cleaning or shampooing, always be sure to extract as much fluid as possible from your carpets. This can be time-consuming, but the results are worth it. Once extraction is done, you should not be able to place your hand on your carpet and come away with a wet hand. A slightly damp hand is fine, but no visible wetness. If wetness exists, perform extraction on the carpet again. A dry carpet is a happy (and non-smelly) carpet!
There are federal and state requirements to reduce VOC emissions.
