Aqueous Cleaners
Aqueous Alternatives for Cleaning Measurement Instrumentation Rosemount Aerospace Inc. is a large manufacturer of air data instrumentation used on both commercial and military aircraft. This MnTAP intern project tested aqueous alternatives to the chlorinated solvent used for cleaning two key instrument components.

Aqueous Cleaning Equipment Manufacturers Aqueous cleaning equipment suppliers offer a wide range of cleaning equipment and related accessories.

Aqueous Parts Washers for Small Operations Because aqueous parts washers use waterbased chemistries, they can be less hazardous to operate than petroleum solvent parts washers. This fact sheet describes the options available and has a list of suppliers.

Emulsified Oil and Water Separating Products Aqueous cleaning solutions can be contaminated by the build-up of emulsified waste oil. This oil can decrease the solution's cleaning capability. Separating oil from the water is an effective technique for extending the usefulness of process fluid or in pre-treating the wastewater prior to sewering. MnTAP maintains this list of products for separating emulsified oil and water solely as a service to Minnesota companies.

Asbestos
Asbestos Asbestos is well recognized as a health hazard as is highly regulated. Heaviest exposure to asbestos occurs in the construction industry, particularly during the removal of asbestos during renovation or demolition.

Aqueous Brake Washers Aqueous brake washing units use water based cleaning solutions. These solutions are nonflammable and contain little or no volatile organic compounds. Aqueous brake washing units are widely available, perform as well as solvent-based equipment and offer many other advantages.

Controlling Brake Dust to Protect Your Health Some brake dust can be seen when a brake drum is removed from a vehicle and many very small dust particles that can't be seen are also released. These particles may be asbestos. Use these methods to control the brake dust in your shop.
