Why should you ask about green cleaning for your property?

Wikipedia defines green cleaning as follows;
Green cleaning is a term that describes a growing trend in favor of using cleaning methods with environmentally-friendly ingredients and chemicals to preserve human health and environmental quality. Green cleaning techniques and products avoid the use of chemically-reactive and toxic cleaning products which contain various toxic chemicals, some of which emit volatile organic compounds (VOCs) causing respiratory and dermatological problems among other adverse effects. Green cleaning can also describe the way residential and industrial cleaning products are manufactured, packaged and distributed.

Toxicity

Many cleaning products include potentially harmful additives such as chlorines and sulfates. These chemical ingredients break down into harmful substances, which threaten our waterways, fish and other wildlife when flushed into our waste systems. Cleantech’s non-toxic product range doesn’t include chemicals like phosphates, sulphates, petroleum solvents or benzene detergent bases.

Look for the EcoLogo

Environment Canada's Environmental Choice Program ensures that products or services carrying the EcoLogo are leaders in environmental responsibility. This is not only true for the product itself, but can apply to the packaging or to the end product. EcoLogo products and services can improve energy efficiency, reduce hazardous by-products, contain recycled materials or may be reused. When you see the EcoLogo, it is an indication that the product or service has been rigorously examined or tested to ensure that it is a better environmental choice.
