Clean and Green
By Joy Finnegan, Editor
Clean and green. That’s a reference to a story in the Stephen Covey classic, "The 7 Habits of Highly Effective People" and "Clean and Green" is one of many stories in that book. In the story, Covey tasks his son with the upkeep of the family yard and drills into him that his goal is to have a yard that is clean and green. If you have never read the book, it’s a classic not only on being an effective business person, but on being an effective person/parent/partner in general, and a recommended read. The reference to green in the story is simply about the color of the grass. Today the use of "green" has come to mean so much more than the green grass growing in a yard. Over the past 10 years there has been a lot of effort to remove solvents with hydrocarbons and fluorocarbons from cleaners needed for the upkeep of aircraft. Unfortunately, some of the new environmentally safe solvents just don’t clean very well. There are few things that compare with Stoddard solvent or mineral spirits for certain jobs, according to an industry veteran. Nonetheless, we have compiled a group of products that are worth taking a look at for their cleaning ability and for their reduced impact on the environment, not to mention the health of users.
Window Brightening and Bug Smashing from Micro-Surface
Micro-Surface Finishing Products has two new products just in time for spring. WinBRIGHT, a windscreen cleaner that is safe to use on polycarbonate, acrylic, and Plexiglas windscreens, was specifically developed for aircraft transparencies, but can be used on any plastic surface on aircraft, boats, motorcycles, RVs, etc. Other applications include windscreens, convertible windows, bimini tops, aquariums, instrument panels, safety glasses and CDs. The professional strength spray removes dust, dirt, stains, smudges and fingerprints. The company claims that optical clarity improves with extended use. Clean surface with water first, then spray WinBRIGHT onto a dampened flannel cloth and polish into the surface until polish disappears. It contains no wax, solvents or ammonia and leaves no residue or build-up. The company says it is water-based and environmentally safe. WinBRIGHT comes in 8-ounce spray bottles. Micro-Surface is also offering an appearance care product engineered to quickly remove bugs without leaving a residue. The product claims to dissolve and remove bugs without scrubbing. If accurate, it would truly be time-saving product. The directions state to spray, wait and wipe. When sprayed, the company says that Bug Blaster is designed to instantly attack bug proteins and acids without dripping, messy run-off. This would be perfect for use in paint shop environments where run-off needs to be avoided. The product is safe on all exterior surfaces including: plexiglass, polycarbonate, acrylic, glass, clear coat or polyurethane paints, polished aluminum, etc. Available in 32-ounce spray bottles, one-gallon containers and five-gallon cartons. www.micro-surface.com

Spray Nine’s AV-8 Water-Dilutable Cleaning Compound
AV-8 Aircraft Soap is a Type IV, heavy-duty, water-dilutable cleaning compound that qualifies to Mil-PRF-87937. Spray Nine recommends using it in place of several traditional solvents, including mineral spirits and methyl ethyl ketone. A mild pH and low VOC content reduce hazards to workers and the environment. The patented blend of surfactants and corrosion inhibitors provides a broad range of non-solvent cleaning and corrosion inhibition, Spray Nine says. AV-8 can be used on painted and unpainted aircraft alloys. The product is bio-based, meaning it is made from renewable farm crops and includes surfactants derived from sugar, corn and vegetable oil. AV-8 contains no VOCs, no ketones, no carcinogens, and no ozone depleting substances. AV-8 is low emulsifying and will not negatively impact oil/water separator systems and other pollution abatement systems. AV-8 is available in numerous sizes. www.spraynine.com
Water-Based Extreme Simple Green is Biodegradable
Extreme Simple Green is a water-based formula for cleaning aircraft, vehicles, engines, metals, plastics, alloys, and parts. It is a non-corrosive, low-foaming cleaner/de-greaser that will not cause rust or degrade elastic materials such as rubber. The company says it accomplishes this with two high-performance surfactants and a new generation grease lifter/cutter which combine to get the soil away from the aircraft surface quickly and then keep it away so that it can be cleanly rinsed off. Extreme Simple Green’s speed of grease cutting and its high capacity to hold grease, oil and soils in solution during cleaning and rinsing time are the keys to performance. This equals fast cleaning and no-redeposition, but Extreme Simple Green is also able to go into oil/water separators and have oil break from solution.
Extreme Simple Green is safe to put through pressure washing equipment, rack wash systems, dip tanks and parts washers, without any equipment damage. Simple Green says the components of Extreme Simple Green are all low-toxicity compounds and the product contains no "solvents." All of these components are biodegradable and will not accumulate in the environment and rinse-waste can be handled by standard wastewater treatment methods. Extreme Simple Green meets or exceeds current and reasonably anticipated VOC requirements. It also contains no Clean Air Act Hazardous Air Pollutants (HAPs), nor is it a RCRA hazardous waste in and of itself when disposed. www.simplegreen.com
Flitz Polish Keeps Brightwork Shiny
Flitz Metal Polish, a concentrated cream, is used to clean, polish, deoxidize and protect most metal surfaces. The polish can remove tarnish, rust, stains, chalking, lime deposits, heat discoloration, bugs, tar, oil, tree sap, and bird droppings, among other difficult stains. This is a staple in many hangars for cleaning and polishing leading edges, aluminium and painted spinners, propellers, thrust reversers, and exhaust stacks, according to Flitz. The polish is non-abrasive, non-toxic and non-flammable. The company says their polish can also be used on Plexiglas windows and lights to remove fading. Flitz also offers "buff ball" drill attachments (see image below) for buffing and polishing surfaces. The ball fits all drills, air tools, drill presses and bench grinders. The original design is made with Italian viscose fiber, according to Flitz. It’s good for hard-to-reach areas and for textured or smooth surfaces. The ball can be machine washed and reused up to 10 times and will not shed lint, says the company. Flitz polish is available in sizes ranging from a 1.76-ounce tube to a two-pound can. www.flitz.com

Zip-Chem’s Calla 7127 for Bird Strike Clean Up
In 2006, Boeing completed the testing of a Zip-Chem product, Calla 7127, for D6-17487 materials compatibility. Boeing found Calla 7127 to be compatible with the airplane aluminum exterior when the product is in a diluted form, 3.5 ounces per 4.5 gallons of water (0.73 ounces per gallon). Zip-Chem Products is marketing the product. When cleaning the external aircraft surfaces to remove bird strike residue, cleansing agents and disinfectants qualified to the ref/B/document are recommended. However, Boeing does not test any product for substance efficacy against disease agents. Boeing recommends airline operators contact the World Health Organization (WHO), product manufacturers, government agencies or local health agencies for product efficacy. The WHO website (www.who.int/csr/disease/avian_influenza/en/) recommends the use of Virkon, a material that corrodes aluminum. Boeing strongly recommends that operators not use this product. Calla 7127 has been approved for use on CFM/Snecma engines when a bird strike has occurred or when there is suspicion of engine parts contamination. Calla 7127 can be used by local spray or local application with a cloth. The technical data sheet and label for Calla 7127 contain more information about use. A specific procedure will be soon introduced in the AMM and CFM ESM. According to Zip-Chem, Calla 7127 is formulated to disinfect hard, non-porous, inanimate, environmental surfaces such as floors, walls, metal surfaces, stainless steel surfaces, glazed porcelain, glazed ceramic tile, plastic surfaces, bathrooms, shower stalls, bathtubs, cabinets, tables, chairs, countertops, appliances and telephones. It is available in one-gallon and five-gallon pails, 55-gallon drums, 32-ounce spray bottles with pre-metered disinfectant concentrate.
