Ingredients

Water

Bleach

Sodium Hypochlorite

Cleaning Agent

Proprietary Surfactant Blend

For competitive reasons, the supplier of this cleaning agent has asked us to keep the details confidential, and we're legally bound to do so. But we can tell you that it's a cleaning agent (or blend of cleaning agents) that removes dirt and deposits by surrounding dirt particles to loosen them from the surface they're attached to, so they can be rinsed away. And, it has met our strict Greenlist™ standards for health and environmental effects.

Caustic

Sodium Hydroxide

Sodium Hydroxide is a builder that can also be found in detergents and degreasers. It makes a product formula clean better by affecting the molecules in the formula so they work together better. Sodium Hydroxide can also be a pH adjuster that alters the pH of a product to improve stability. Every formula has an optimum pH to make it work best. For example, a formula that’s more acidic works better for soap scum removal. Its opposite, a formula that’s more alkaline, might be more effective at removing grease or greasy soils. We use pH adjusters to make sure we achieve the best pH for a particular job. Also, the pH of a formula can affect how long it lasts within a container – for example limiting its tendency to rust in a can. In high concentrations (such as in drain cleaners), Sodium Hydroxide can also be used as a caustic that helps dissolve organic matter like drain clogs.

Foaming Agent

Hydrogen Peroxide

Hydrogen Peroxide is an alternative to chlorine-based bleach that can also be found in products such as mouthwash, hair products and teeth whiteners. It can be added to household cleaning products to remove or lessen stains and odors. You probably have a bottle of over-the-counter-strength Hydrogen Peroxide in your medicine cabinet, since many people use it as an antiseptic as well. It can also be used to make foam, or as a stabilizer to maintain a product as it is exposed to air, light, or heat.

Corrosion Inhibitor

Sodium Silicate

Sodium Silicate is a corrosion inhibitor that can also be found in laundry detergents, dishwashing detergents and hard surface cleaners. It helps keep metallic household surfaces such as faucets and drains free of corrosion.
